galivan
A galivan is a guy or guys who can't decide on a song or a car. They wear girls' skinny jeans like they're trying to be fashionable and have hair that looks like it came from a raccoon and a dirt pile.
'My neighbor's a galivan. He drove my car, played 9 songs, and still couldn't pick one. I'm still mad.'
'I dated a galivan. He wore my jeans and told a joke so bad it made me cry. I'm still mad.'
'Why is there a guy with a dirt stache in my car? He must be a galivan. He even told a joke that made me laugh until I cried.'
