Seen commonly throughout college campuses, house parties, and clubs; D bombing is when you walk up to a girl on the dance floor and start kissing her without warning.
"Wait so how did they meet?"
"One night he just d bombed her."
A d bomb is a method of taking the drug mephedrone, also known as drone, meow, mcat etc. Some of the powder is put into a bit of paper, normally a cigarette paper, and is folded up to about the size of a tablet. It is then swallowed and ingested to hit the user harder than when snorted.
Mate, I want to d bomb the rest of this drone so I can get fucked!
