when you are trying to think and you are a little slow

A word used to indicate that a person or thing is cool. Should not be confused with the meaning of "fuck" relating to sexual intercourse.

an action, thing, place or person who is not quite able or practically worthy to be fucked for copulatory or procreatory purposes for all intents and purpuses; but is rather fuckable for the sake of argument.

Strong exclamatory agreement, often to an unusually concise or precise statement or proposed course of action.

This is the correct spelling - beware the overformal 'fucking a', taking time to pronounce the g is a profanity faux pas and de-emphasizes the strong expression of agreement - you might as well say "jolly good show", queerbait.

Also beware dropping the apostrophe for the omitted g, just because we're using profanity doesn't mean we need to do it like an illiterate.

"Fuckin' Awesome"

Can be said in good or bad context to indicate a positive or negative reaction (respectively), but no matter how it's used... it still means "Fuckin' Awesome"
