A low self-respect guy that dates and keeps company of a women that he likes. But, she only using him temporary until she meets her new lover. Once she meets her lover, the guy leaves and the seat is warmed for the new lover to sit in.
Omg... That guy again, you know he follows you around like a lost puppy. Once you get a new guy, tell that seat warmer to fuck off.
