Refers to the tightness of a girl's vagina. If a girl has a loose vag, she is said to have very little (if any) tread on her tires.
Hey, how was hooking up with Sarah last night?
Let's just say there's no tread on the tires.
She was that loose?
It was like throwing a hot dog down a hallway.
Gross.

A zombie-like stance that treadmill users take when they grip the treadmill screen and walk.
This stance is typically used by people who are new to the gym or don't work out often.
Not necessary for people who don't user walkers in real life.
