Gravity Well 

Used to describe the fat girl in a relationship with a really skinny guy.

This phenomena is explained in physics by the attraction of lighter objects in space to heavier ones. Like the earth and it's moon.

This orbit is usually quite unstable. It can deteriorate when the large object feeds the smaller object to a point where he creates his own gravity well, or it can be broken by excessive ridicule from the smaller objects friends.

The gravity well is becoming more and more prevalent in Australian R&B clubs where skinny Indian students hook up with big girls in an attempt to emulate the African American penchant for large booty

"Look at that fat emo with the skinny indian she has him firmly captured in her gravity well."
