Males if they aren't frat boy types.
Females if they are tom boys.
The reason why I like tom boys is because they are generally less catty and don't obsess about weight and take swipes at you for being thin. I like to be around people that know I'm not out to make them feel like s**t and in return I don't want them to treat me like s**t. If they haven't made it to friendship level and they display this behavior, they won't make it to friendship level unless we are forced to hang around each other and eventually click together (it's happened before)
The reason why I don't like frat boys is the way they speak drives me up the wall, they can't be bothered to have an intelligent conversation and they seem to have trouble taking no for an answer so you have to punch them and only then they get it.
