When a guy ejaculates in a person's mouth and that person has braces.
Person 1: hey, I was with Kayla last night and I blew it in her mouth. She's nasty.

Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.

Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
