(Random Baseline Skanker) - When your out in a club or pub you often come across lone women who just can't help but move their bodies to a filthy base line. Often found around Dubstep. These girls are often found sweaty and dehydrate from to much alcohol but the chances are a friend or your self will fancy your chances.
Oh my god Hugo did you see all the RBS come out in that club last night when they played the Dubstep!?''

Raging Boner Syndrome

When one conceives of a boner that results in a massive erection that is capable of being seen from under layers for clothes.
"I had RBS the other day at dinner, and I couldn't get up to walk without having to think of Ellen Degeneres, the Zima man, cow manure, and my mom naked."

Restless Booty Syndrome-n- A condition in which one is at work or school (particularly in an office, classroom, or some other employ that involves extended periods of sitting) where the patient can no longer sit still and must shake their rump, like a salt shaker, in the immediate vicinity of said workplace. Music, particularly that which initiates from the "dirty south", can be used as an aid. Symptoms include (while seated) shifting from one cheek to the other, head bopping, raising the roof, head swaying, popping and locking, the robot, the arm wave, and randomly shouting out, "can I get a dance groove in this bitch!" If you feel the onset of any or all of these symptoms you should immediately: 1.shake that ass; 2.watch yourself; 3.shake that ass; and 4.show me what you're working with.
Heather and Trisha were working on an important research study when Heather began throwing her hands in the air indicating that she did not particularly care for working on her assigned task any longer. Confronted with the onset of Heather's RBS, Trisha immediately started playing the Ying Yang Twins and they both proceeded to shake their groove thang.

An acronym for the phrase "Rough Bum Sex". This is additionally comical because the Royal Bank of Scotland (also RBS) logo resembles an anus.
John Doe enjoys RBS.
