Latest slang terms

5head
Gaming
A Twitch emote of a streamer with an enlarged forehead, used to praise a genius play.
5-out
General
Heads-up shouted across the line that a dish (or a whole table's worth of dishes) will be ready to plate in five minutes. Gives the rest of the brigade time to fire sides, warm plates, and get servers in position. Swap the number for any countdown — 10-out, 3-out, 2-out — and the meaning scales with it.
4pf
Street
Lil Baby's Atlanta label and brand — '4 Pockets Full', shorthanded everywhere on chains, hoodies and ad-libs. Stamps everything his camp puts out.
4head
Gaming
A global Twitch emote spammed as a reaction to a joke, often a bad or obvious one.
420-friendly
Street
Describes a person, rental, or space that permits or is comfortable with cannabis consumption.
404 moment
General
The moment on rounds when the chart, the file, the scan, the lab result — none of it can be found. Not in the trolley, not on the system, not at the desk. Borrowed straight from the HTTP 404 'Not Found' error, deployed with a sigh.
404 coded
Internet
A blunt, digital-native insult for being out of touch or oblivious.
40 mike-mike
General
A 40mm grenade or the M203/M79 grenade launcher that fires it, 'mike-mike' being phonetic shorthand for millimeter.
3s and 8s
General
A friendly sign-off between operators, meaning best regards and best wishes. Comes from old amateur radio Q-code shorthand: '73' meant 'best regards' and '88' meant 'love and kisses.' CBers shortened both into 'threes and eights' as a way to wrap up a conversation warmly without getting soppy about it.
3hunnak
Street
Anti-300 / anti-GBE chant from the GD side of the drill war. Lil JoJo took Keef's '3Hunna' and slapped a K on it — the K does the same work it does in GDK or BDK: killer, opp. Still gets shouted by anyone repping against the 300 camp.
3hunna
Street
The phonetic, lyric-friendly version of 300 — Chief Keef's shorthand for his Black Disciples set on Lamron. The 2012 track 'Three Hunna' is the reason kids who've never been to Chicago shout it.
360 flip
General
A technical trick in which the board completes a full 360-degree shove-it rotation combined with a single kickflip. Synonymous with 'treflip.'
30k millionaire
Street
A Dallas-coined insult for someone making roughly thirty grand a year while living like they make ten times that. Leased Benz, designer fits, bottle service at Uptown — all stacked on credit and vibes. The city basically invented the term to roast its own culture of appearance-over-substance.
30,000-foot view
General
A high-altitude overview that ignores fine detail to see the whole landscape.
2nite
Internet
A numeronym for "tonight," substituting 2 for "to." Common in early SMS.
2-for-1
General
A late-clock tactic of shooting early enough to get the ball back for a second attempt before the period expires.
1cc (one-credit clear)
Gaming
The gold standard in shmups and retro arcade games. You start the game, you finish the game, and you do it without ever feeding it another coin. One life pool, no continues, no second chances. It's the line between a casual player and someone who actually beat the game.
12th man
General
The supporters whose noise and energy influence a game so much they act like an additional teammate.
10k collection
Internet
An NFT project consisting of around 10,000 individual, trait-varied tokens generated from a shared template; the standard format for PFP projects.
100-footer
General
A lesbian whose vibe is so loud you'd clock her from a football field away — the carabiner, the walk, the energy, no words required. Equal parts joke and compliment. In 2025 it came back swinging as a celebration of being instantly, gloriously legible.
100 mph tape
General
Heavy Army-issue tape, said to hold up at a hundred miles per hour, used to fix nearly anything.
1-up
Gaming
An item or pickup that grants an extra life. Grab one and your life counter ticks up by one. The original safety net.
0dte
Internet
'Zero Days To Expiration' options that expire the same trading day, offering explosive gains or total loss within hours. The purest form of WSB gambling.
051ym
Street
A Gangster Disciples faction out of the 051 area of Chicago's South Side, named as opps in countless Black Disciples / O'Block drill tracks. King Von built half his catalogue around dissing them.
