When the target of your affection will not do anything with you without the inclusion of his/her best friend.
Steve: Hey, there's a concert this weekend. Wanna go?
Alice: What about Stephanie?
Steve: What about her?
Alice: Well, I can't leave her out.
Steve: But this is like supposed to be a date, you know? Just you and me?
Alice: No Stephanie, no me. YOU BOY!

Burt: So, what happened with you and Alice?
Steve: Man, she wouldn't go if Stephanie wasn't invited too.
Burt: OH FUCK. THE PACKAGE DEAL.
