The sound that one makes when irritated, frustrated or just pissed. Very popular in the urban world. Sounds like a leaking tire.

A prank where you step on the back of somebody's shoe and make it fall off.

Variations:
1. Sandals. It is difficult to flat-tire a sandal, so a different strategy must be used. One way is to kick the sandal out. Occasionally, for fat, loose sandals, the normal method for flat-tiring works.
2. Boots. It is practically impossible to flat-tire an Ugg boot, so what you do is keep stepping on the shoe until it breaks, then they have to get new ones & you can flat-tire those.
3. Backpacks. When you flat-tire someone for quite a while, they become aware of you, but you've got another trick up your sleeve! Pretend to flat-tire that person, they'll dodge their shoe. At that time pull the back of their backpack & everything falls out.
I flat tired this kid and we started playing monkey in the middle with his shoe.
