mooberboating 

Mooberboating is the act of motorboating moobs. It's like motorboating but on men's boobs. This act can be done by a male or female but is commonly done as a joke in gay circles.

Damn. Did you hear about Tony? Well he's on a mooberboating streak, so watch out.

Manterboating

The placement of one's face, into the cleavage of a man's moobs, followed by the side-to-side shaking of the head accompanied with a motor-ing sound.

John made many trips to McDonalds on Friday; resulting in a hefty, yet delicious figure. Sarah was captivated by his rolls and decided manterboating his moobs at the pool the next day would be a hot idea.
