A person who is attracted to every new hot person they meet but is a total mess about it, whether it's by coming on way too strong or by being unbearably awkward. Either way the result is pure chaos
A bisexual who may often find themselves in the friendzone. Alternatively it may be any hot mess of a person who tangentially also happens to be bisexual.
I might be in love with my work-wife but I'm not sure if it's just friendship or not and I'm afraid to even ask what her orientation is. She asked me what mine is and I told her 'disaster bisexual.'
