A term used to describe two men, usually underage, who are attracted to one another but don't want to ruin their reputations by admitting their homosexuality for one another. So they spend the rest of high school crushing on each other without realizing that their feelings would've been returned, if only they had been brave enough to admit them.
Guy: You know those two guys in the sophomore class, James and Michael?
Girl: Oh, them? It's so obvious they like each other
Guy: Yeah, but they're both too scared to admit that they're gay for each other. They're such a Habifittz
Girl: That's too bad. I hope they won't stay a Habifittz for the rest of high school
