Doing absolutely nothing while hanging out with your friends but talking about it like it's really cool and you HAD to be there. Does not refer to something perverted that Steve Carrell said.
"Hey Bree..I had an awesome time at that pants party"
"Yeah, we should totally get together and have another one"

The conversation is loud so as to attract others attention. Then when they question about the "party", you tell them that they have to be at one for a true experience.

A great way to break the ice when performing an awkward sexual act. ex, double team, orgy etc..

Everyone takes their pants off and relaxes, until you decide to take it further.
Hey man, I hear you double teamed that slut last night. How'd you start it off?

Simple man, a pants off party!
