flying Philadelphia fuck
The same thing as flying fuck, only emphasized.
I do not give a flying Philadelphia fuck about you! Fuck a tree, asshole!
Philadelphia Flying Fuck
Involves a doorway, a rocking chair, a chinning bar in the doorway. The man puts his knees on the chair. The woman sucks his cock by rocking the chair, when he's about to blow his load, he hangs from the chinning bar, heightening orgasm
I'm all worn out from that Philadelphia Flying Fuck last night
