Brotorboat 

v. int. The act of a man pushing one's face in between two ample man-breasts, and rocking one's head side to side very rapidly while making a vigorous, lip-vibrating "brrr" sound.

Wouldn't you love to see Ryan Seacrest brotorboat Meatloaf?

botormoat 

A "reverse motorboat". Achieved by burying one's face between a supple set of buttcheeks and rapidly shaking the head from side to side. Optionally, one may purse the lips and blow out while botormoating to emulate the sound made by a motorboat's engine.

Johnny's girlfriend didn't have much of a chest, so he flipped her over and botormoated her.

Broderboat

When someone is holding two dicks beside their mouth and alternating their lips backs and forth on the dicks resulting in a “der-der-der-der-der-der-der” sound.

Not to be confused with Broterboat, which is when someone’s face is being slapped by two dicks simultaneously or in an alternating pattern.

Sharon loves to broderboat Tyrone and Maurice.

Maurice and Tyrone broterboated Sharon last night.
