Panty Fap 

When an individual with a panty fetish incorporates panties into their masturbatory rituals. This may include, but is not limited to, wearing panties, sniffing panties, shoving panties into a bodily orifice or holding panties in their fapping hand and physically wanking with them.

I stole some of Rachel’s undies last night out of her gym bag. I’ll be doing a panty fap tonight.

He wrapped the pair of lacy panties around his engorged knob and busted one out from a panty fap.

Fap Party

When you and a couple of friends get together to watch porn and fap to it. It is only gay if you look at each other, if not then it's perfectly not gay.

1: Y'all wanna have a Fap Party?
2: Ain't that gay?
1: Only if we look at each other.
2: Cool, cool.
