Treadmill Bitch

A person (most times a girl) who buys a gym membership, regularly goes to the gym and only run on a treadmill. In many cases the person is on the phone or speaks to a friend quite loudly.

The plural form is Treadmill bitches where girls come in groups of about 3-8 and either occupy ALL treadmills or stand around the treadmills.

"I ran next to a treadmill bitch earlier. She was on the phone all the time and didn't stop talking for one second!"

"So last night i hit the gym and i couldn't use the treadmill for an hour! The place was covered in treadmill bitches!"
