belt tuck 

When an unexpected erection occurs, the act of tucking the boner upwards in its natural direction, held close to the stomach by the belt/ sweat pant elastic. Makes public erections virtually unnoticeable. A shirt is mandatory

Just Tuck It 

When a man has to pee sitting down, he has to tuck it in order to prevent accidental pee-leakage.

Caleb: Man, I just peed sitting down for the first time ever.
Caleigh: How does that even work....like, do you just tuck it or what?

Bat Tuck 

The Bat Tuck is when you pull your testicles over your penis(stretching them like a Batwing, hence the name) over the tip of the flaccid penis, this anchors your testicles to your body, avoiding the irritation of perspiring testicles, itchy testicles, etc. Or at least avoiding the the most intense effects of leaving your testicles in their normal position.

I did the Bat Tuck so that I could sleep. It was so humid last night, and I really need to shave.

Squirrel Tuck

When the dude’s nuts are pushed and tucked in her pussy or ass during coitus.

I couldn’t believe it braaaahh. I was banging Rachel from behind and she reached under, grabbed my balls and did the squirrel tuck. She said that should be enough for the winter.
