Uncle Mark 

An extremely hairy man who is sometimes mistaken as Sasquatch. He is often found with a half empty beer can in 1 hand and a lighter, which is never his own, in the other.

That crazy "Uncle Mark" is so hairy & appalling, it looks like he has a sweater on when he's really fukn topless

Gay Uncle Mark 

A gay uncle Mark is the uncle everyone thinks is gay but can’t admit it to himself. He would have a funky beard and a ponytail that looked like 3 hairs on a horses ass. Typical phrase used would be “Hey mmmaaannn” When laughing he would make the sound of a gay rabbit humping another gay rabbit. Take caution when around people like this. They are easily subdued by the elusive catfish.

I would invite you all over... but I have a gay uncle Mark hangin around
