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

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

Blue Submarine No. 6

Blue Submarine No.6 is a pretty badass anime about the once famous and well respected scientist Zorndyke who has bred a new genre of living being, one that thrives on the oceans and lives to destroy humans. Zorndyke believes it is time that the humans were relieved of their rule of the earth. It is up to Blue Submarine No. 6 and the rest of the Blue fleet to put an end to Zorndyke's madness and creations.

Blue Submarine No. 6 used to come on Toonami on Cartoon Network back in the day.

Brown Submarine

A feacal deposit left in the toilet bowl following an unsuccessful flush. Due to the density of human excreta these visual obscenities usually reside at periscope depth. Simple post-flush checks by the degenerates that leave them behind would render the Brown Submarine a thing of the past.

Bridge Officer: Captain! Bearing 030 off the starboard bow. Brown Submarine!

Captain: Set Depth Charges to Zero...Fire 1...Fire 2...

Bridge Officer: ....Enemy flushed sir.

Captain: Good work sailor, the Rear Admiral will be pleased.

submarine races

"Watching the submarine races" is a euphamism for making out (and more) in a car. It's the kind of thing a cop would say to be funny when he knocks on the fogged-up window of your chevy parked in back of the safeway to ask what you're doing there at 1am, as if he doesn't know damn well.

Cop: Hey, what're you kids doing in there? Watching the submarine races?
People in car: Gak! Where are my pants?
