submarining 

Like motorboating, but on a vagina. Bonus points if your head is literally underwater, like in a pool, bathtub, or jacuzzi.

“Dude! I went submarining on Alina last night!”

“That’s awesome!”

“Too bad I nearly drowned, on the fact that she got horny while we were in the hot tub.”

Submarining 

Blowing air between the testicles of your partner. The male version of a motorboat.

Tom loves it when I am submarining while jerking him off.

Submarining 

When you motorboat someone's ass cheeks making a sound reminiscent of an angry Richard Nixon.

I motorboated her, but she wanted more, so I plunged down below because she needed some submarining.

submarining with the cosby kids 

Submarining with the cosby kids means diving down as deep as you can, dropping some logs, and then racing them back to the surface.

Not so cool in a public pool.

Serena was totally impressed with how deep Larry could dive, until the dooks started surfacing, and she saw that he'd been submarining with the cosby kids.

She didn't leave a note.

Submarineing 

When you pack as many people as possible into a mini van, with enough weed as you can get and all start smoking at once. the ratio of people to smoking paraphernalia should 2:1, but more joints, bowls, bongs, and hookahs never hurts. The point of the submarine is not to be moving but to find a safe spot and fish bowl it so bad that you take a hit just by taking a breath and make it hard to see in from the out side from all the smoke.

Side note: Always remember to bring food and drinks in the van before you start smoking

the smoke was so thick when we went submarineing last weekend, that you literally couldn't see your hand one foot in front of your face

A man capable of submarineing is capable of any atrocity and is not fit to command.
