underboobing 

The act of hitting the underside of one's breast with ones head in one swift motion

"I keep getting underboobed!"
"When he underboobs me it hurts!"
"For some reason she enjoys underboobing people"

Underwooding

Banging a girl freakishly hard.

Matt gave Emily such an underwooding that she couldn't walk for 3 days.

underboobage 

The southern hemisphere of a woman's breasts, as often displayed to the delight of virile men.

I love to see the underboobage of buxom females playing volleyball in the sand, especially whilst wearing all-too-short crop tops. Oh yeah, neathage!

Underlooking

When you are viewing something from a lower position - the opposite of overlooking.

At basecamp , underlooking the glorious mountain.
