If your friend rages during a friends' game of versus, he is not your friend. This happened to me last night. A friend invited me to a lobby with 2 of his friends, one of who was absolutely immature (the ones who spam and can't relax). My friend asks me to invite people I know, so I invited couple of total pros on my team. The immature guy didn't want to wait for my friends and wanted to pubstomp. I told him to calm the F down. Anyways, the game of dead center starts. The immature guy tries to deathcharge me, misses, goes out the window, splat. He starts cursing me (???) in caps as to why I moved and dodged his charger. jeez. We all make it to the end, and in our turn as infected, I was a charger. In a sweet turn of events, I knocked the immature guy out the ledge along with his buddy. 2 insta deaths. Holy crocodile tears!
Anyways, the "friend" who invited me kept wanting to go back to lobby in Dead center 2 and said he didn't wanted to play, and finally ragequits. We all knock the piss out of the immature guy and he ragequits in his waaahmbulance too. I soon removed the friend from my buddy list. Soon the lobby is pubbed, and we change teams to balance the power and we have a tremendous game of fun. Anyways, sorry for the rant I just wanted to let it out. If someone from your buddy list ragequits, remove them!
