An insult used to emasculate men. It combines two of the greatest oppositions to hetero-males, homosexuality and things that are cute and fluffy. It is most effective against males who claim to be heterosexual, yet engage frequently in questionable acts, and least effective against those who are actually gay.
A person who acts amazingly stupid in the most hyper active ways. Most people who are like this will have lack of sugar intake or people who get easy sugar rushes. If you think you know someone who is a Wigglemuff the main symptoms are: 1. They act really daft at random moments 2. They will have a history of anger issues 3. And finally they will act out no matter what the situation.
"Man that guy was totally hyper last night, but he was acting really stupid at the same" "Yeah he was being a total Wigglemuff"
