A semi-fictional word made up to describe in extreme disgust those formerly referred to as creepers and stalkers. This was in response to the adoration/appreciation of certain stalkers and creepers, who felt it was necessary to create a new term for the unappreciated stalkers and creepers.
Girl: Aww, Matt, you're my creeper. I love you.
Matt: Yes, I am pretty awesome.
Randomly appearing brecko: Yeah, get some!
Girl & Matt: ...Gawd, such a brecko.
