The "ring" of fat wrapping around the mid-section, caused by lack of self-respect and being abused as a child. -used to roll oneself down hills when tired.

a bulge of fat around the waist

The huge roll of fat that often times drapes off of a woman's frame because she is so fucking fat and/or drinks to much beer/eats too much pizza, tacos, enchiladas, pasta, or cake. It can be best seen on college girls wearing tight shirts which they intend on showing off their "hot bod," but actually end up showing some nasty flab going about the entire circumfrence of their mid section, or at this point more like mid country they can be so large .....

the flab around the stomach that can stick out over a women's jeans. obtained by overeating, not excercising enough, or drinking too much beer.

HOWEVER... can be kindof cute on the right woman

In hold'em poker, a starting hand of Jack/Four. As in, "What's a Jack for?"

Playing off the expression third wheel, fifth wheel, etc. A spare tire is a person (male or female) that you bring with you on a date. If the date falls through or you're not having fun, you rely on the spare tire to get you through the night.

A woman that you use when your old one is getting repaired or you are waiting for a new one.

Similar to a third wheel, but instead of one couple and a single person, there are two couples and a single person. The name comes from the fifth wheel in a car, or the spare tire.
