Slang, short for "destructive rampage". Specifically, a d-ramp is when a group of people go around their town and fuck a lot of people's shit up. Lawn ornaments, those glass, colorful balls that people put in their yards(gazing balls), mailboxes, and cars are just some of the things that get fucked up. Usually, a d-ramp consists of 4-5 people who are really pissed off or really bored.
"I got a lot of anger built up!"
"You know what that calls for....."
"What....?"
"A d-ramp!!!"
When walking along in a dense crowd with someone else, to cut through a small opening between people (to pass them) and leave the rest of the party behind because the opening closes up as soon as they cut through.
"Why the hell are you still way back there?"
"Because you Cruz Ramirez'd me when we were crossing the road and I couldn't catch up, ya dipweasel."
