Mumster MUM-ster Noun. SLANG Referring to an unattractive, gross person that only a few people find attractive. Also, someone who thinks they're much more attractive than they actually are. Not to be confused with "munter" which is British slang for an unattractive woman. DEFINITELY not to be confused with the Munsters, that TV show from the 60s that starred Fred Gwynne (for anyone under 50, he was also the judge in My Cousin Vinny) . Mumsters BARELY rate above a 5/10 and if you're really a good person, you won't let your friend go home with one. For example, Mumsters usually wear straw cowboy hats. You might be able to hear a murder (flock) of Munsters from afar if they are, "woo-hooing" or yelling any of the following, "that's what she said", "get 'er done", "Vegas baby, Vegas" or "I'll sleep when I'm dead." Let's get Mumster in the lexicon! Spread the word, NO MUMSTERS. Coming soon, a t-shirt shop: www.nomumsters.com Remember: only YOU can prevent Mumster babies.
