"K" Terms

k-fan
Internet
A domestic Korean fan, whose spending and voting carry outsized weight for domestic charts and awards versus i-fans.
k-netz
Internet
Korean internet users whose forum and portal reactions strongly shape idols' domestic reputations, distinct from 'I-fans' (international fans).
k-whopper
General
Affectionate CB-radio nickname for a Kenworth truck — usually the long-nose W900, the chrome-fronted American icon. Kenworth drivers tend to be loyalists, and the K-Whopper has a near-mythic status in owner-operator culture: expensive, beautiful, holds its resale value, and looks right doing anything.
k&b purple
Street
A specific deep royal purple, named for the Katz & Besthoff drugstore chain that drenched the city in it for most of the 20th century. New Orleanians use it the way other people say 'Tiffany blue' — a precise color reference everyone local instantly clocks.
ka kite anō
General
A friendly farewell meaning 'see you again'. Often shortened to 'ka kite'.
kabedon
Internet
The romantic-drama move where one person slaps or leans a hand on the wall beside another, trapping them in place — an iconic shoujo 'wall slam' moment.

General
The everyday Kiwi word for food, used interchangeably with 'food' in casual conversation.
kaiju
Internet
A giant monster that rampages through cities, a genre and creature type central to tokusatsu and much anime. Literally 'strange beast'.

By extension, the gifting ritual itself — trading kandi is a peace-and-friendship handshake in the scene.

A prison officer. Formed by rhyming slang stacked on top of 'screw'.
kangaroos loose in the top paddock

Used of someone who is a bit mad, eccentric or not thinking straight.

Internet
Emoticons built from characters that are read without tilting your head, such as (^_^) or (>_<), heavily used in anime-fan chat.

Drop it at the end of a sentence and you've just put air quotes around the whole thing. It means 'don't take that seriously, I'm being ironic.'
kapusta
Internet
Russian slang for money, literally 'cabbage,' echoing green-vegetable money metaphors.
kara cancel
Gaming
You start a move that scoots your character forward a touch, then cancel its first few frames into a second move before the first one fires. The second move now reaches from that further-forward spot. Free extra range.
karen
Internet
A meme archetype for an entitled, complaining person, classically a middle-aged woman who throws a fit over minor issues and demands to speak to the manager.
karma
Internet
On Reddit, the running total of upvotes minus downvotes your posts and comments have collected. It's a meaningless internet number that people somehow still fight over — high karma signals you've been around, posted bangers, or relentlessly farmed easy subs. Required to post in some communities, used as a vibe check everywhere else.
karma farm
Internet
A post built like a slot machine — designed to print karma rather than say anything real. Reposted wholesome dog pics, recycled inspirational quotes, low-effort 'Reddit moments' — the genre is wide. The point isn't the content, it's the number going up. Often a prelude to selling the account later.
kawaii
Internet
Shorthand for an entire aesthetic of pastel colors, plushies, and round cartoonish charm.
kay-li
General
Sherbet powder — the brightly coloured, slightly sour stuff sold in paper bags by the quarter from old sweet shops. A Black Country / West Midlands word, peak nostalgia for anyone who grew up in the region between the 40s and 80s. Spawned the related 'kaylied' — drunk — because the buzz feels similar.
kaya
General
A term for marijuana, immortalised as the title of Bob Marley's 1978 album 'Kaya'.
kaylied
General
Extremely drunk — well past tipsy, into the can't-stand-up zone. Stronger than 'bevvied'. Heavily Scouse and Northern English, with the same energy as 'hammered' or 'paralytic'. Origin is murky but possibly linked to 'kali', an old sherbet sweet.
kda
Gaming
The three numbers that sum up your game at a glance. Written like 10/2/8 — ten kills, two deaths, eight assists. Often crunched into a single ratio: (kills + assists) divided by deaths.
kday
Street
1580 AM KDAY — the first US radio station to go all-hip-hop, broadcasting out of LA from 1983 to 1991. Broke NWA, Ice-T, Run-DMC and the whole West Coast scene. Re-launched on 93.5 FM in 2004 as a classic hip-hop station and still name-checked on records to this day.
kecks
General
Trousers. Standard Scouse and northern English usage — jeans, joggers, work pants, all kecks.

To peep or glance quickly, often slyly; as a noun, a hasty look.

keep dixie

Standing watch. The job of the mate who isn't doing the crime but is one whistle away from saving everyone. Could be a school nick, a corner-shop swipe, or just texting your dad while you sneak back in. Whoever's keeping dixie is the eyes.

keepie-uppie

keeping sketch
General
Acting as a lookout — standing watch while a mate does something they shouldn't. The classic schoolyard sense: one kid robs the apples, the other keeps sketch for the teacher. From the Irish word 'sceith' (to reveal, to inform), filtered through generations of cute hoors.
keffel
General
An old, worn-out or worthless horse — a nag. From Welsh 'ceffyl' (horse), but in English it picked up a sneer: the second-rate, knackered, sorry-looking kind. Once common in 19th-century underworld slang for a dodgy mount; now largely obsolete, but still rattles around in horse country and historical fiction.
keg
General
Another word for a barrel or tube of a wave. The pun on a beer keg is very much intended in surf culture.
kek
Internet
Means laughter. Originated in World of Warcraft, where Horde players typing 'lol' had it auto-translated to 'kek' for Alliance players. Escaped into Twitch, Discord and 4chan chat where it stuck. Carries slightly more 'laughing AT you' energy than plain lol.
kekw
Gaming
Can carry a slightly mocking edge, laughing AT someone's fail rather than just with the joke.
kekwait

Past tense and participle of 'ken'; 'I kent that' means I knew that. A 'weel-kent face' is a well-known one.
kerb crawler
General
A client who cruises red-light streets in a car at walking pace, sizing up workers through the passenger window before pulling over to negotiate. Mostly British usage; the activity itself, 'kerb crawling', is a specific criminal offence in UK law.
