The abbreviated form of "wait, why don't I have a boyfriend?" which is said out loud, or to one's own self, after doing something disgusting, perverse, vulgar, etc. that most men would find absolutely repulsive.
After dropping a huge TSR I wondered aloud, "WWDIHAB?" Is this why? Yeah, probably.
the abbreviated form of toilet shit rape, filling a toilet with the most disgusting shit ever, resulting in your toilet feeling completely violated afterward to the point where it may file claims of domestic and sexual assault against you.
Dude, my toilet just TOOK IT with the TSR that I just laid down.
