"F" Terms

forever alone
Internet
The early-2010s meme persona of the perpetually single, perpetually rejected guy. Used self-deprecatingly when something romantic falls apart, when you spend Valentine's by yourself, or when you third-wheel hard. Equal parts joke and cope.

Utterly worn out, exhausted or in a sorry state.
forfochen

Opposite, facing or over against something.
forsen
Gaming
Used to reference a raid or spam wave, as in being 'forsen'd' by his community.

Gaming
An emote spammed when something on stream breaks or doesn't work as it should. The go-to 'it's broken' reaction.

foul trouble
General
When a player has accumulated enough fouls to risk fouling out, forcing cautious play or bench time.
found family
Internet
A group of unrelated characters — or real people — who bond into something that functions like family. The whole appeal: nobody had to love each other, they chose to. It's the emotional core of half of modern fantasy, half of queer media, and most ensemble shows worth watching.
four wheeler
General
From a trucker's seat, the world divides into rigs and everything else. 'Everything else' is a four wheeler — your car, SUV, pickup, whatever. Said with the faint condescension you'd expect from someone driving 18 wheels who has to deal with civilians cutting them off all day. Often paired with a warning: 'four wheeler in your blind spot, driver.'
four-bagger
General
A home run, so called because the batter touches all four bases ('bags') on the play.
four-top
General
A four-person table. Same logic as two-top — tabletop plus cover count. Servers love them because the tip scales but the trips to the table don't.
fourth point of contact

A euphemism for the backside, from parachute-landing-fall doctrine, which counts the body's points of contact with the ground on landing — the fourth being the rear.

fox in the box
General
A sharp, instinctive forward who uses clever movement to lose markers and pounce on chances inside the box.
foxing
General
Pretending to be asleep, knocked out, or otherwise unaware — usually to avoid a cell search, a fight, a count, or an unwanted visitor. The fox plays dead. In prisons it's also used when an inmate fakes out after a kicking so the screws think it's worse than it is.
foxtrot

fractionalization

frago it

Informal verb use of FRAGO — to modify an existing plan or order quickly with a fragmentary order rather than issuing a whole new operations order.
frajo
Street
A cigarette. Old-school Chicano street word for a smoke — the kind you bum off the homie outside the liquor store.
frame advance
Gaming
An emulator feature that pauses the game and lets you push it forward exactly one frame per press. The bread and butter of TAS work and frame-perfect glitch hunting.
frame thysen
General
An instruction to pull yourself together or get on with something properly. Broad Yorkshire.
frame trap
Gaming
A sequence of moves deliberately left with a small gap, just big enough to look mashable but tight enough that any button the opponent presses gets counter-hit. Bait into punish.
frame-perfect
Gaming
A trick with a window exactly one frame wide — at 60fps that's a sixtieth of a second. One frame early or late and it just doesn't happen. Brutal to land consistently by hand, which is why these are the moments that separate the top runners from everyone else.
frankerz
Gaming
A classic global Twitch emote showing a dog's face. Chat throws it out for cheeky sarcasm, playful vibes, or just to spam a wall during hype moments and raids.
franklins
Internet
Slang for $100 bills, named for Benjamin Franklin.
frap roast
General
Starbucks-specific. A concentrated instant-style coffee powder dissolved in water to form the coffee base of a Coffee Frappuccino — used instead of brewed coffee or espresso because espresso would melt the ice and wreck the texture. Customers asking for 'extra coffee' in a Frap usually mean an extra pump of this.
frappe
General
In Boston, this is a proper milkshake — milk, syrup, AND ice cream blended together. Order a 'milkshake' in Boston and you'll get just milk and syrup, no ice cream. Pronounced 'frap', one syllable, no fancy French ending.

freckling

freebander
General
An operator who's hot-rodded their CB radio to transmit on frequencies just above or below the legal 40-channel CB band — typically the 'freeband' between CB (11m) and 10m amateur. Bigger range, juicer signal, totally unlicensed, and an FCC fine if you get caught.
freelancing
General
Acting on your own at an incident instead of staying with your crew and following the incident commander's plan. It's the cardinal sin on the fireground: nobody knows where you are, nobody can save you when it goes bad, and you blow up the accountability system the whole operation runs on. Freelancing shows up in the cause-of-death section of more LODD reports than almost anything else.
freestyle
Music
As a verb, to freestyle, to do anything off the cuff without a plan.
freeze
Gaming
A laning technique where you only last-hit minions instead of killing the wave, keeping it parked near your own tower. The enemy has to overextend to farm, leaving them exposed to ganks and denying them CS.
