Latest slang terms

muffuletta
Street
A massive round loaf of sesame-topped Sicilian bread split and layered with mortadella, salami, capicola, mozzarella, provolone and — the non-negotiable part — a briny chopped olive salad that soaks into the bread. Cut in quarters. One sandwich feeds a family.
muff
General
When a player touches a kicked ball while trying to catch it but fails to secure possession, making it live.
muela
General
Smooth, persuasive talk or flirtatious flattery. 'No te dejes llevar por su muela' = don't fall for his sweet talk.
mudman
General
Site nickname for whoever's working the wet stuff — joint compound on drywall seams, or plaster on lath. Overlaps with taper but skews older and broader. If there's a bucket of mud and a hawk in his hand, he's the mudman.
mud duck
General
If you sound like you're transmitting from the bottom of a pond, you're a mud duck. Weak signal, garbled audio, the kind of voice the other drivers have to strain to hear. Could be a bad antenna, low power, or just a long way out. Said more in pity than in malice — unless you're also a bucket mouth, in which case good luck.
muckle
General
Large or great in size or amount; 'mony a mickle maks a muckle'.
muck stick
General
A shovel. Same job as a goon spoon, different flavour of insult — this one is about the mud, slurry and general muck you're going to be relocating with it. Heard a lot on civil, drainage and groundworks crews.
mre
General
The 'Meal, Ready-to-Eat,' the individual packaged field ration, joked about with backronyms like 'Meals Refusing to Exit' and 'Meal, Rarely Edible.'
mra
Internet
Someone who identifies with the men's rights movement — usually framing men as the systemically disadvantaged side in custody, suicide rates, false accusations, conscription, etc. The Southern Poverty Law Center considers parts of the movement misogynist; supporters argue real issues get drowned out by the label.
mr. drummer
General
Mr. Drummer was the heavier, more fetish-forward cousin of IML, named for Drummer — the most successful American leather magazine. Drummer launched in 1975 in Los Angeles, moved to San Francisco in 1977 after police harassment, and ran its International Mr. Drummer contests there yearly from 1981 until the magazine folded in 1999. A note: it's sometimes mis-dated to 1979, but the contest itself started in 1981.
mps
General
Muscle Protein Synthesis, the process by which the body repairs and builds new muscle protein; protein intake and training drive it up.
mowdie
General
A mole; 'mowdiewort' is the fuller form.
moving the chains
General
Gaining a first down, which requires the chain crew to reset the 10-yard chains to a new spot.
moving mad
Street
Acting in a way that is out of order, reckless, or disloyal.
movida
General
A move, scheme, or shady side deal/affair; 'movidas' are shady dealings.
move the needle
General
To create a change substantial enough that people or metrics will actually register it, typically on a KPI. If it doesn't move the needle, it isn't worth doing.
move the dial
General
To produce a change large enough to be noticed on a key metric, used interchangeably with 'move the needle'.
mouse jiggler
General
A hardware gadget or software tool that moves the cursor automatically to keep a computer 'active' and simulate that a remote worker is present and working.
mouse
General
A small foam or felt plug — sometimes a wad of plastic bag — shot through an empty conduit with a vacuum or compressed air, dragging a pull string behind it. Once the string's through, you use it to pull the actual wires. Called a mouse because it scurries through the pipe.
mounting
Gaming
Planting your weapon on a wall, ledge or window so recoil drops and your aim steadies. Turns a spray-happy gun into a laser for holding angles.
mouldy
General
Hammered. So drunk you've gone off, like food left out too long. Common across Ireland — nothing to do with fungus, everything to do with twelve pints and a shot of Jameson.
motorized freckles
General
Soldier slang for flies, fleas, lice, and other insects that swarmed troops in camps and foxholes — a dark joke about specks that moved.
moto
General
Short for motivated. In the Corps it almost always lands sarcastic — the boot who irons creases into his cammies, the lance corporal who quotes the rifleman's creed unprompted, the guy with the Eagle-Globe-Anchor tattoo before he's even left MCRD. Genuine moto exists; it's just rarer than the mocking kind.
motion
Street
Making money or progressing successfully in business, music, or hustles.
