The Term used when you have two (male or females) where one rude ugly girl has a really hot best friend. The term package deal is used when some one only wants the hot girl, but you can only get her through her best friend therefore you invite her to invite her hot friend. It can sometimes be risky because if you attempt package deal and get her to invite her hot friend, her friend may not be able to come, and so you can sometimes get stuck with the ugly girl. But if it pays off, it can definitely be worth it.
Dave: Hey lets call up some girls to hang out!

Dave: Ehhh, Its risky.. But I'm feeling pretty lucky!
