Originally an aeronautical term that is the equivalent to the modern "Loud & Clear". In slang usage, it means "great, fine"; popular in New England, it was made famous in "Buffy: the Vampire Slayer" from its overuse by the rogue slayer Faith.

Verb -- Freaking out or tripping on drugs, usually psychadelic mushrooms or hallucenogens.. Inspired by the song "Five-Five-Five," by Frank Zappa. The instrumentals tend to inspire people to take drugs. Once in a state of inebriation, the maddening guitar riffs of "Five-Five-Five" make Phish look like O'Dweeds compared to the wicked buzz you cop from Frank's Fiver. Which is ironic, because Frank Zappa was very much against drugs.

Also simply referred to as Fiving, rolling with Frank's bunch, or 2F.
"Yeah, man, I was totally Five-Five-Fiving it last night with Frank's bunch. Had like, fifty mushrooms and some beer, man. It was like getting a year's worth of pussy in four minutes. Uh... what was I talkin' about, man?"

"No way! You were 2F without me, man!? Dude, I so hate you now! Just kididng, brah."

Taking someone to school in the art of foos by scoring on five consecutive shots -- the more variety the better. This is especially effective when done in the context of a booking, or when capped by a money shot.
Ain't nothing like going five-for-five against Pooch, nearly putting his eye out with the money shot.

Get the five by five mug.
A tool used among friends to retain possession of a certain seat. As the name suggest, fives only works for five minutes. After standing up from his chair, the person announces "fives", and then can freely do what he needed to, and when he returns no one is allowed to take his seat during his absence.

Powerful foe of, "you move your feet, you loose your seat."
Rudolf: I need to pee, fives.

==four minutes later==

Rudolf: Get your ass out of my seat.
Schwartz: No Way!
Rudolf: I called fives, schmuck.
Schwartz: ... arr, you got me this time.
