Guy 1: I know man, I'm out!

While playing Halo 3, you hammer on the "B" button to lay a melee smack down. At the exact same instant your opponent also hammers on the "B" button and you beat each other down. This is often followed by a "You asshole" as well as "instabeat"!

Joe - "Hey Bob did you see that we both beat each other down in Halo 3."

Bob - "Yeah that was massive INSTABEAT! you R-Tard. Did you see what I did to your sister as well?? INSTABEAT!"
