treadmill season 

around mid-November to early March, when it becomes too cold to continue to run outside and you are forced to move your runs inside to a treadmill.

Oscar, the buff guy who works at the gym: Haven't seen you in a long time, mate.

Dakota: Came to hit the treadmill. It's treadmill season.

Oscar: Cheers!

treadmill metal 

Heavy, thrash-death metal music that although going very fast, doesn't seem to go anywhere.

Dude, this band's guitars are tight but it is total fucking treadmill metal.

Treadmill Dick 

After sex or a blowjob, feeling the sensation of the act hours after it's happened- similar to getting off a treadmill and still feeling like you're on it.

"My girl just gave me the best head, like, an hour ago. Now I've got treadmill dick"

Treadmill Argument

An opinion driven argument that goes nowhere and solves nothing, typically religious or political in nature, made by people who only think they're correct.

Do you want to actually figure out what's wrong here, or exercise your mouth with this treadmill argument?

Treadmill Pinch 

A Treadmill Pinch happens when you try to have sex with the gap between your treadmill and the floor, then by some mistake the treadmill is turned on and it rips your foreskin off giving you a Jewish trim.

Example: you hear about Johnny's Treadmill Pinch? There's still foreskin all over his workout room
