The much less wimpy sounding version of bundle.

That guy who is an awkward addition to any conversation, plan etc.
"Why was Joshua with us at dinner the other day?"
"I know right? He invited himself to our plans at the last moment."
"How awkward, especially after what he said to Kate last week! Such a pile on!"

Pile On - "sexual definition" - to have more than 2 people join together on a bed, rug, or elsewhere for the purpose of engaging in group sex or group sexual intercourse.

Usually associated with group sex, swinging, swingers, the lifestyle and other free-thinkers.
Linda and Jim were fucking naked on the bed. Debbie got undressed and joined them. Then John walked in, got naked and asked if he could pile on. They all shagged and reshagged for hours. The swingers piled on each other all night.

I stopped at a rest stop on the interstate and the toilets were full of poo, so I got stuck piling it on.

To sit on the couch in semi darkness for hours on end, ordering food, consuming various and sundry pills, avioding all cell phone calls, while being in a state of semi dress and watching massive amounts of TV (if one can retain consiousness).
