The intense itch that occurs when one sits in a boat for too long after swimming
Dude why can't you sit still
I've got boat butt
When one gives another a rim job, but lubes it with maple syrup.
She gave me the old Manitoba Motor-boat.
The act of dipping your face into another mans penis and nibbling on his sack.
"Boys...it is man-boat time XD"
The act of motor boating ones buttocks.
She had small boobs so I ended up butter boating her instead.
