Top definition
An operation in which one repeatedly gives away high-calorie treats such as muffins, cookies, and donuts to one’s friends, relatives, and associates to fatten them up, so that one appears thinner in comparison.

Rumor has it that the singer Mariah Carey has a policy where other women appearing in her music videos must be fatter than she is so that she appears thinner in comparison.
