Seatbelt Nazi 

A person who absolutely, positively refuses to start the car until everyone therein is buckled in, even if in a state where it's not required by law, and who will castrate her boyfriend if she sees him in any car unbuckled (This is to say 99.9% of all females.)

My girlfriend cut me off for a whole month because she caught me in an Uber without a seatbelt on. She was so angry I'm lucky I still have my both my testicles. What a seatbelt Nazi!

Stonewall Seatbelt 

Rudimentary device for securing a lose penis. To create this device, a string is tied around preferably the foreskin or head of the penis if foreskin is not present. The other end of the string is attached to an anal toy of some sort. When the anal toy is inserted in the user's anus, the string will pull the dong between the legs and across the gooch, securing the penis in place.

Damn Mike's dick is so big I heard he had to use a Stonewall Seatbelt just so he is able to wear shorts.
