"K" Terms

kinfolk
General
Inside, kinfolk is how Black inmates often refer to one another — and how the wider yard taxonomy slots them, the same way whites are 'woods' and Natives are 'chiefs'. Carries family weight rather than insult; you call your kinfolk because you're expected to ride for them.
king cake
Street
An oval braided cinnamon cake glazed with sugar in Mardi Gras colours — purple for justice, green for faith, gold for power. A tiny plastic baby is hidden inside; whoever gets the slice with the baby has to buy the next king cake. Eaten only between Twelfth Night (6 January) and Fat Tuesday.
kingpin
General
The large central bolt of a skateboard truck that holds the hanger and bushings in place and can be tightened or loosened to adjust turning.
kink
General
A bend or change of angle in a rail, or an uneven, non-smooth section of a feature, which makes it harder to slide cleanly. Kinked rails are among the trickier jib obstacles.
kip
General
Sleep in general, often in 'getting some kip.'
kippered
General
Wiped out, exhausted, finished. The kind of tired where you sit on the edge of the bed and just stare at the floor for ten minutes.

kirkifying
Internet
The act of using AI face-swap tools to paste Charlie Kirk's face onto reaction images, viral clips and unrelated memes. A textbook transgressive-meme trend — half the engagement is the shock that people are doing it at all.
kiskadee
General
A common noisy bird (Pitangus sulphuratus) named for its call, with a bright yellow breast.
kiss
General
Apply the lightest possible touch — a few seconds under the salamander to warm a plate, a whisper of salt, a quick brush of oil. The whole point is restraint: if you can taste or see it clearly, you overdid it.
kiss me neck
General
An exclamation of shock or amazement, like 'good gracious!'. Also 'kiss mi neck back'.
kiss teeth

To make the sucking-teeth sound ('cho!') expressing contempt, irritation or dismissal. Also 'suck teeth' / 'kiss mi teet'.

A chest or large box; in mining, the deputy's office box.
kite

kiting
Gaming
Move-attack-move. Fire off an auto, step back, fire again — keeping distance between you and whatever's chasing. Ranged carries live and die by it.

klein's
General
Lineman's pliers — the chunky side-cutting pliers electricians live by. Klein Tools so completely dominated the category that the brand became the tool. Saying 'pass me the Klein's' on a job site means the pliers, even if they're a different brand. Like Hoover for vacuum, Kleenex for tissue.
