1) Gathering of douches in a secluded area.

2) Party in which the only people that show up are complete douches, making the party very douchelike.
1) "Look at that douchey douche-a-palooza of douches over there douching it up."

2) "Where is everyone?!?!? God, this party is such a freakin douche-a-palooza!"

Get the douche-a-palooza mug.
When a crowd of four-five douche bags are isolated from a crowd, (with the exception of a couple of outsiders) and are trying to "show off", impress somebody, or are just being plain douchey.
Bob, Steve, Peter, John, and Vincent are playing basketball and keep trying to hit three pointers, but they're totally failing. Don't get me started on the way Peter tripped while doing a layup trying to impress Sheila. Can you say douche-a-palooza?
