Jimmy Party 

When the party your friends throw is full of mostly male populates. Every one at the party has a "Jimmy". Or the only people invited were Jimmys (male). Or possibly more common, a guy named Jimmy invited all guys.

Your friend invites people to your house but only guys come. You say it looks like we are having a Jimmy Party
