"Philldup" is a catch phrase that a famous homosexual slut named Fillup uses after getting his ass inseminated by ten anonymous men through a hole in a wall.
Fillup: Hi I'm Fillup and i just got my asshole and throat philldup by ten unknown men through a hole in a wall at a gay night club about a year ago. And that C.U.P. was a nice touch too. I hope i don't get aids.
