Bistek
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.
"Jes sir can you pease give me an order of tacos de bistek"
