Get the monstermug. A potent, tasty, liquid concoction of caffeine, sugar or sugar substitutes, taurine among other strange and harder to pronounce substances. Often gives the drinker a rush of energy, and an all-around good feeling but leaves them with an epic crash. Comes in many great flavors including Khaos, Assault, locarb and even Java varieties. To some its addictive as crack.
Me:Dude that guy is all strung out on  Monsters, I think that's his third one today.
John: Holy crap that is a big can.
Tim: Yeah its the BFC Monster...BFC get it?
John: Oooohhh, (chuckles).
