I live with three guys, and as the only girl, they tease me a lot. One night, we went to a party with guys my roomies knew from high school. I hit it off with one of their friends and brought him back to our place while the guys were still at the party. We were in the middle of hooking up when they came home. They must have realized what we were doing because they stood at my door and started loudly singing their high school fight song. The worst part was that the guy I was literally straddling started singing it back to them.
