Both in my case.
I'm wondering if Drunk TF2 would be a good idea...
Play Control Points with a friend in his dorm room, and we take shots when we lose/win a control point.
See how bad we end up getting.
Last time we played in his room, we stole furniture from the lounge [Which could get us both in serious trouble, considering there's this one RA who writes people up for the smallest things, like the time another friend sat on the security monitor's chair in the lobby.] to make a gaming area in his double mini-suite. It was kinda epic. We had a face to face situation, and in-game we did a Medic-Heavy pair, so he could literally watch my back, and it make it harder to sneak up on me since we had verbal communication.
