A mixed drink modeled specifically for gamers, namely those who play Halo and Halo 2. Made by combining Bacardi 151 and Mountain Dew. Great for late-night Halo 2 Live sessions. Also great for vomiting.

when a chick is sucking you off and you are about to finish you back up and run at her while jacking off and melee her w/ said cock and you shoot your load all over her for dramatic effect. Warning may only work on drunk girls, also spraining of the cock may occur when melee'ing bitches. have fun!!!
Sally is giving an awesome Blow J but you think she needs to be taken down a peg or two, so when you think your done you pull out run at her and while shooting said load onto face you melee her as hard as you can possibly trying to cum in mouth as well. master chief

The most amazing soldier in all of history. As a Spartan II, he was trained to be the best soldier ever. He has saved thousands of galaxies and planets, and is definitely better than Spartacus, pie, the muffin man, and cute puppies. Do not anger his epicness.

Ladies: OMFG!!!!! SIGN OUR BODIES IN PERMANENT MARKER!!!!!!!!
