When you have a large machine gun in a First Person Shooter video game, and you hear an enemies footsteps, so you run around the corner and shoot left to right in a chainsaw fashion and yell/type RAMBO'D!!!!
I created this when me and my brother were playing Counter Strike on LAN, and I heard him, so I jumped out from around the corner and shot everywhere and yelled RAMBOOOO!!!
So instead of saying Rambo, I decided to turn it into a verb, like Rambo'D. Same as saying Pwn.
Machine Gunner: Dude, you got totally rambo'd!
Sniper: I know, I was not expecting that ramboness!
sneaks it in the back door and then when hes just about finished, he comes around the front full blast and outta control!
"damn bitch! you a mess! like your ass got rambo'd"
this term originates from the mean streets of glen burnie maryland.
