When 4 people (guys or girls) tap it with 1 person in the middle. Similar to the Eiffel tower, but with a lot more people.
"Ah man! It was this one broad and 4 other guys doing a circus tent with that girl!"

When you give the person next to you at a pinic table a hand job. Picnic table cloths are usually red and white, giving the illusion of a circus tent. Judging by the movement of the tent you can tell how many rings it is.
"Did you see that girl pitchin' that circus tent, it was at least three rings"
