A nonexistent word originating in the southmost tip of Texas. Beef Steak is thinly sliced meat used on a local cuisine called Tacos. The raza of the region can't pronounce beef steak because they got too much of Mexico in them.....so it comes out as Bistek instead of Beef Steaks.
Bastard spoken in a northern US accent, especially relevant when the subject is a really big bastard who likes to tout his bastardom all across Midamerica
"Eric, you faggotty-ass biested, why don't you go and have anal sex with a horny South American goat, as such is your preferences."
"Why yes, such an act is my preference, seeing how I am a true biested"
