Let me see if I got this right. You're at a party enjoying yourself when two girls you don't know from a hole in the wall, come up to you and demand you drive them back home to their dad. So, if you don't drive them home, you're holding them against their will? Huh? Double huh?

You left out the part where their dad shows up and you and your friends surround him to prevent him from taking the girls home when they are requesting to go with him.

No, the father burst in demanding to know who was hosting an underage drinking party. This is when the frat guys allegedly surrounded him- which I assume 99% of people would do when a raving lunatic they don't know confronts them.
