Imitation is the most sincere form of flattery, right?
There are certain things that I just find completely repulsive in girls. Dense, frizzy, scraggly hair is one of them. I'm sure women have similar things for men, and since I bet 90% of them are easily fixable, I'm curious what they are.
(This thread is supposed to be focused on aesthetic things - that is, physical features, body language, fashion, etc. However, if you really want to talk about personality or the like, feel free to.)
