Pile On 

When everyone jumps on top of one unfortunate soul, they 'pile on'.
The much less wimpy sounding version of bundle.

'Look, Chris is asleep. Pile on!'

Pile On 

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 

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.

pile-on 

Usually found in a hardcore show, a pile-on is when everyone rushes from the pit to the front of the stage and jumps on the shoulders of the person in front of them. This is done mostly during a sing-along where the vocalist gives up the mic to the crowd, much like a gang vocal.

Dude that pile-on during Mutiny was fucking croosh!

It is when you and your co-workers decide to drop dueces into one bowl, and to never flush it all day long.
