Motor boaters 

The medium- to large-sized breasts of a woman when clothed by a low cut garment that only extends superiorly as far as the widest point of her bust.

Can predispose the bearer to nipple slip.

"So I'm just trying to work, and in she walks with these motor boaters, all cooing and jiggling, and I about f*!cking lost my mind!"

The act of motorboating your 2 week long girlfriend on your trampoline the same night you invited all of your friends over to watch movies in your backyard.

Maverick: "Dude I motorboated Kristen on friday!"

Friend: "When?"

Maverick: "On the trampoline during the movie lol"

Friend: "WHAT! YOU MAVERICK MOTORBOATER!"
