BFFCY

big fat fuckin cock, yeah - an expression of extreme joy, ususally repeated over and over and faster and faster until the words become undistinguishable to the point where only the letters can be used; also sometimes recited while making a fake moustache with a finger. Moustache is in reference to popular economics teacher who believed BFFCY to be particularly funny.

"Big Fat Fuckin Cock Yea... Big Fat Fuckin Cock Yea Big Fat Fuckin Cock Yea, BigFatFuckinCockYeah BiFaFuckinCockYea BiFaFuCoYea BFFCY BFFCY BFFCY... what do u think dr. miller?"
