Who was Tubgirl?
I will answer in RDB3's absence. Tubgirl is not a FReeper, but the title of a sick picture that the racist/porn lover poster has posted from time to time. It is not something you want to see.
Check the first result on Google some time when you're not at work.
The most maddening aspect of these threads is the allusion to these horrible pictures without actual descriptions or links.
