Adj. When a man is not gay but just doesn't like girls in that he finds them attractive but not as a necessity. However not in an asexual sense, a qualm person just does not put forth the effort or time into getting a girl.
Usually describes a goodlooking guy that could get girls but just doesn't.
Damn, that dude could get so many bitches if here weren't so qualm.
Qualm is derived from the lynd cross and is commonly used as a term to say lets do it, lets sort it out, basically just lets get on it.the word can be used in many forms either when discussing buying something, organising a night out, something sexual, etc.
For example, lets go to the pub- lets QUALM the pub OR when inviting a lady friend back it is used in this sense- lets qualm it back to mine (please note this works 9 times out of 10)
