Beefer

A term used to categorize a female of substantial size and weight. Unlike your standard run of the mill fat girl, Beefers avoid whale-status by engaging in minor physical activities such as running on the treadmill in ten minute intervals, erotically dancing at frat parties, and vigorously waving their arms as they bitch about their relationships (or lack thereof). Beefers travel in herds (also known as beef stampedes) and can reduce a solid B+ party to a C- in as little time as it takes to fit them all through the front door.
