Disposable White Guy and I were playing Crimson Skies on the original Xbox, when he became so frustrated that he threw my dinner plate-sized Xbox controller at my sliding glass door. Almost hard enough to break it.
All-time favorite story also involved Disposable White Guy and my brother, all three of us vacationing at a beach house at the Outer Banks in North Carolina.
I had brought my Xbox, so we could play Halo when the weather was ugly. That day, it was overcast and drizzling off and on. So instead of lugging our chairs, towels and beach paraphernalia to the ocean front, we stayed inside and played Halo. Three guys, no teams - total free for all. My brother was in high school at the time, so his videogame skills were still quite raw and he was easy pickings for veterans. Disposable White Guy and I, on more than one occasion, double teamed him.
We did this a few times, and he began to protest, his voice cracking with each plea of, "Stop ganging up on me!" This only fueled us to continue ganging up on the teenage lad. At one point, we hijacked both Warthogs and took turns running over him when he respawned. He began to tear up, so we stopped our shenanigans and focused on the game.
He still kept dying, not out of coordination, but lack of skill.
At this point, he shrieked like a girl - in the middle of the match - and threw down his controller. He stomps over to the system, in the middle of play, and yells, "I'M GOING TO THE BEACH!" and unplugs the system. He storms out of the house, and we watch from the second floor window as he marched angrily in the rain (in late afternoon, no less) towards the beach.

The imagery of him walking to the beach, along with, "I'm going to the beach!" became something of catchphrase with us for whenever we became frustrated with something. For my brother's part, after the debacle, he became something of a TacFag® disciple and honed his skills to the point where neither Disposable White Guy or myself can beat him at any shooter nowadays.
