I had a similar experience playing Halo last week.
My friend and I were in a game, and one of our teammates quit before the game started so it was 4 or 3.
The teams were:
Us: Major (me), Major, Sergeant (friend)
Them: Brigadier, Major, Captain, Lieutenant
We were playing on Snowbound, and we played it like we play every game on Snowbound - on the surface, killing at medium range with BRs and carbines. We don't hide in the cave like a bunch of pussies, and more importantly we don't attempt to go into the cave when our enemies are hiding like a bunch of pussies. We'll throw grenades to flush them out and shoot them from the cave openings, but that's it. We force them to face us on the surface like men.
We were dominating pretty well until our score hit the mid 30s, then they got smart and started running in a pack of 4 at all times. We weren't sticking together, so it was pretty easy for them to pick us off one by one that way. We regrouped in one of the bases, not intending to stay there, but they surrounded us. Then they started coming in after us with no coordination at all - one, two at a time. We kept killing them, and they just kept coming. I died at one point and started killing them from the outside while the other two guys on my team were inside. They were split up and focused on my teammates, so it was easy. We ended up winning 50-42. Their brigadier and I both had 20 kills and 15 deaths. His teammates were all negative, my teammates were +2 and +1.
We were happy, and we moved on. In the middle of our next game, my friend and I both got invites from the brigadier and the major from the other team. Then he got a voice message from the brigadier and I got one from the major (the major was -7, the other two guys were -4). After we finished our game we listened to the messages. They were full of profanity, called us pussies, blamed their teammates for the loss (remember, my message was from the worst player in that game), demanded a 2v2 rematch. I messaged my guy back and told him (politely) that it wasn't his teammate's fault. He sent me another message, again full of profanity, called me us pussies again, etc, etc. I messaged him back and told him (politely) to stop getting so worked up over a game.
