A person (typically male) who refuses to engage in normal romantic relationships. They are sometimes referred to as "emotionally unavailable" and tend to lie, cheat and manipulate women until the woman is whipped into a state of complete confusion and suicidal tendencies. Often times the unsuspecting female is initially lured by very romantic, passionate, hot behavior only to be met with ice once she starts to expect some of the lies the assclown has dished out.
