The reading of a Blackberry Messenger message and not responding. Clearly denoted by the "R" and "Checkmark" beside the message of the sender.

Usually a sign of disrespect towards the sender of the message.
"Did you ask Natalie if she is coming to that party tonight?"

"Not sure I sent her a BBM; she read it, but didn't respond."

"Dude she totally R-Bomb'd you."

"Bitch!"
