1. People who have LOST in LIFE! Someone with no prospects who is clearly going to amount to nothing in this world. Immature, cocky, superficial, dickhead, horny, pathetic, self-centered DUMBASS smoker guys with NO personality who have no interest in anything that's going on in the world and waste everybody's time, space and air. Expect to be respected because they're supposedly 'hot' or have a 'hot' car, or screwed some 'hot' girl. People who need to learn how to control their libido. They think its 'cool' to use and abuse females. Usually spend all their time making crude physical assessments on women and in many ways further objectifying them. (usually butt ugly, but THINK they're good-looking)
2. Anyone who has ever raped a girl, and who probably smokes and does other DUMBASS things.
loser: "Hey, maybe if I tell her she has nice tits, she might be impressed by my feeble attempt at masculinity and forget that i have no brain and no life and smell like cigarettes."
