"M" Terms

me resbala

An emphatic 'I don't care at all' — it slides right off me.
meal prep

Slang for a heavily muscled gym-goer stereotyped as caring only about lifting and not much else; can be affectionate or mocking.
meatspace
Internet
A slightly ironic term for the physical, offline world (your body being 'meat'), contrasted with cyberspace/the metaverse; synonymous with IRL.
meaty
Gaming
You space or time a move so it connects on its last active frames instead of its first. The opponent eats it the instant they rise, and you get way more frame advantage — sometimes enough to combo off it.
mebbees
General
Maybe. The classic Geordie hedge — non-committal, often doubled up ('mebbees aye, mebbees naw') for full effect. Same shrugging vibe as 'I dunno, like'.
mecha
Internet
A genre and design category built around large robots or mechanical suits, often piloted into battle. Gundam, Evangelion and Code Geass are landmarks of the genre.
medevac
General
'Medical Evacuation' — the movement of the wounded or sick using dedicated, marked, medically equipped vehicles or aircraft crewed by medical personnel who provide care en route.
medibles
Street
Cannabis-infused foods, especially those consumed for medical purposes; a blend of 'medical' and 'edibles'.
medical futility
General
The concept, and bedside shorthand, that further intervention cannot achieve a meaningful outcome for the patient.
mee6
Internet
A wildly popular Discord bot that handles auto-moderation, welcome messages, XP/levels, music, and reaction roles. So ubiquitous it's basically generic — 'add MEE6' often just means 'set up a basic server bot,' regardless of which one you actually pick. Has a vocal hater contingent over its paywalled features.
meet
General
To French-kiss someone. 'Did you meet anyone?' at the end of a night out is not asking who you bumped into — it's asking who you got off with.
meff
General
A dirty, smelly or badly-dressed person — used as a proper insult. Liverpool-specific and properly cutting. Originally meant a tramp or vagrant; broadened to anyone scruffy or socially undesirable. Don't call someone this lightly.
megacreeps
Gaming
Kill every rax on the enemy's side and your creeps get upgraded across all lanes — bigger, tankier, harder-hitting. Megas pile pressure on every lane at once and can siege a base on their own if the enemy doesn't defend.
meganekko
Internet
A female character whose defining charm point is that she wears glasses, treated in fandom as its own attractive archetype.
megs
General

To relax and become calm, easing off anger or anxiety.
melon
General
An air in which the rider grabs the backside (heel) edge of the board with the leading (front) hand. Short for 'melancholy.'
melt

An affectionate jab between mates for being soft.
melt up

A deeply annoying or irritating person who wears you down.
melts

Said of a gun with brutal damage-per-second. Point it at someone and their bars disappear like ice on a hotplate. The mark of a meta weapon.
meme stock
Internet
An equity whose price action is driven by viral attention — Reddit threads, TikToks, Twitter pile-ons — rather than earnings or business performance. GameStop and AMC are the archetypes; any forgotten ticker can become one if the meme catches. The defining feature: charts that look insane to traditional analysts and totally logical to anyone who was on r/wallstreetbets that week.
memecoin
Internet
A cryptocurrency that originates from a meme or humorous concept and derives its value mainly from social-media momentum and community rather than utility. Dogecoin is the archetype.
memphis underground
Street
Umbrella tag for the gritty, lo-fi cassette-era Memphis hip-hop scene of the early-to-mid 90s — horrorcore, pimp shit, devil shit, all stacked on cheap drum machines and crunchy 808s. DJ Spanish Fly, Tommy Wright III, Three 6 Mafia in their tape days, Playa Fly, Kingpin Skinny Pimp. The DNA of every phonk beat you've heard on TikTok.

merk
General
To beat, batter or thoroughly defeat someone. Standard roadman vocabulary for losing a fight, a rap battle, or a FIFA match — anywhere one party gets dismantled.
mermaiding
Internet
