The submarine game 

The player lays on their back in the bathtub and attempts to make only the tip of their dick peek out of the water like the periscope of a submarine.

Mai: You sure took your time. Were you thinking about me or something?...

Sakuta: Actually, I was just engrossed in playing the submarine game

If You are the Dominant or Top in the situation it is Your responsibility to see your play partner through this period of chemical dis-balance and or depression and make sure they are safe, sane and healthy.

Bat Submarine 

When someone makes a comment and someone else repeats it soon after, claiming it as their own. Often, but not always, trying to one up the original idea.

Emmet - We could build a submarine!
*short delay*
Batman - We could build a Bat submarine

submarine shot 

Similar to a "floater shot" aka "floater", but at the bottom of the cocktail.

Tamara: My husband was lit last night, I apologize for him at the wedding, he was plowed and loud.

Brie: I had a blast with Adam - classic Adam. He was ordering everyone bushwhackers with floaters, though ordering his bushwhackers with a submarine shot as well as a floater!
