Finally later that morning they had a winner, but because of what happened they decided to play it again the next morning. A girl called up with her girlfriend and proceeded to motorboat her. The guys on the station were drooling over this whole bit. I however was still puzzled, even after listening to the motorboat.
I broke down and asked my friends to please clarify the situation... and I'm still laughing about what it is!! For those of you who are puzzled:
Proper Motor boating etiquette dictates that a woman squeeze her chest together and upwards allowing ample room for another party to raspberry them vigorously.
