RDaBS is an acronym for Restless Dick and Ball Syndrome. It is an affliction that occurs in high humidity when the skin of your ball sack sticks to the inside of your thigh. What separates this from normal leg-sticking is the tenacity in which your sack adheres. During a bout of RDaBS you can be expected to have your hands on or around your nuts for the better part of the attack.
Q: "Yo, why are your hands in your pants?"
A: "I got a bad case of RDaBS."
"My RDaBS is flaring up."
