Bullets. Used in Call of Duty (and other shooters) cuz you pretty much have to go Rambo in single player to get anywhere, or the enemies just keep coming. Used in sense of automatic weapons, as that's pretty mush all Rambo used.
(Playing Co-Op Call of Duty 5)
Guy #1: Damn, I'm getting points like crazy!
Guy #2: Yo, move up! I'm almost out of Ramboes!

(In a video game) Rushing headlong into the enemies and attacking wildly, usually with total disregard for the game state, their strength, your strength, your teammates or the map objective, especially if you immediately die and even more so if this outcome was obvious to everyone else in the match.
We could have won this game but this noob Reinhardt kept ramboing into the Bastion so we had no tank most of the time.
