When you take 2 pulls of a 'bifter' in quick succession and you go all dizzy and and it basically feels like you are getting high from the cigarette. Excited, hyped, tingly feeling throughout the body.
Boy 1: 'arr lad, take 2 pulls quick and you go on biffter buzz and you go fucking dizzy'
Boy 2: 'i feel dizzy lad, I must be on bifter buzz'
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.
