When performing oral sex on man who is sitting on a wooden chair, the partner will suddenly take the man's nuts and slam them as hard as possible against the chair in a attempt to force a painful ejaculation . This was popularised in Philadelphia through a social media challenge.
My girlfriend was giving me some good head when suddenly she threw me a Philadelphia Slammer, it was so painful that I cried like a baby.

A drink that will get you shit faced faster than you can say "oompaloompa". Basically, passing around 40s of Steely until you hit the bar code and then refilling it with Sparks. Tastes nasty, but you get drunk to the point that it doesn't matter.
After killing the second sidewalk slammer, Tim and Jane had blackout drunken sex and woke up the next mourning in one another's barf.
