A phrase used to describe both agreement and disagreement, both happy and unhappy sentiments. It basically is used if I want to put extra emphasis on whatever I'm saying.
"Fuckin A, that is way too much tuna!"
I have seen definitions of this phrase that say the "A" stands for both affirmative and awesome, but I'm gonna say it stands for "Amen".
"Fuckin A, I shit my pants and it smells terrible, but I would rather sit here in my own mess, sipping off my flask, then get up and clean myself. Here my friend, you want another shot?" I said, holding my flask out to my buddy.
"Fuckin Amen to that!" He replied.
"Fuckin A, that damn dog will not stop humping my leg" OR "Fuckin A that little mutt knows how to shake its bow-wow booty! I wanna get fuckin crazy up in that!" "Fuckin A dude, that's gross."
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.
