Seat-Belt Titty's

When a female has her seat-belt on and it crosses between her boobs making them look bigger in size which would later create a boner for the guy sitting in the car next to her looking at them.

"Hey Chubb's look at blonde in the car next to us. She has some awesome seat-belt titty's. I'd sure like to stick my cock between them"

Seat-filler 

The people in your class who never do anything gossip-worthy and therefore are just there to fill the seats. These people may also be called hoverers. They know everything but do nothing.

Georgia: "Leah just stans around us while we eat lunch. I feel like she knows more about me than I know about myself"
Amy: "Yeah she's such a seat-filler!"
