the effect brought to you by mixing red bull with whatever alcohol you find in your cabinet.Its a cliche,kind of like how cowboys get a horn up there ass during a rodeo.
man,I was up all night drinking vodka,rum,and tequilla mixed with red bull and I feel like shit.Oh,well,I guess if you play with redbull,you get the Red bull horn.My girl got the "horn" last night too.
