Top definition
A Feemster is one person in a group of overweight and obnoxious people. They are known to talk at extraordinary high decibels and snort like pigs; often interrupting others with nonsense. They are generally unreliable and make up excuses to try to cover their own. Spending time with a Feemster is a overwhelming experience; you often feel as though you are at the petting zoo, playing with Hyenas.

Feemster is also used as a verb to describe the act of duping and confusing someone, or royally screwing them over.
