Someone who is straight that 'crashes' on gay affairs. They think they understand gay people but are generally just annoying and are very often women that want the novelty of a gay best friend.
"hi mike, can i come out wth you and paul tonight?"
"you know we're going to a gay club right?"
"yes"
"but you're straight"
"yes but i'm open. I'm not prejudice"
"no, you're just a gaycrasher"
