Random Occuring Boner. This usually happens when a hot ass girl walks by you in the middle of class, you look at her, and POOF. Instant boner and instant embarrassment. Congratulations my friend, you have a ROB.
Tyler: "Dude, you need to get your ROB under control."
Grant: "Ahhhh man, she's so hot though. Oh shit, look away!"
Tyler: "That was disgusting as fuck, man."

Synonymous to 'rage'.
Hence, to 'Rob' is to rage, and gives rise to such terms as 'Rob quitting' and 'ROB ROB ROB ROB'
Rob: "Guys, I'm not in the mood"
Someone Else: "That's what she said"
Rob: "That's it, I'm out."

*Server: Rob has left the server*
Someone Else: "Dude awesome he just Rob quit.

Acronym for "Randomly Occurring Boner." This is when a male gets an erection in a non sexual situation, usually in awkward or inopportune times.
I don't know if I can hire you Mr. Peterson, as you had a ROB for most of this interview.
