"That Guy" (or Girl) is a term that can have both a positive and negative connotation.
To get the negative over with -
That Guy who...
- continually doesn't call his hits (and will get lit up by someone eventually!)
- continually gets angry when shot (Last I heard it's the nature of the game. That's like playing tackle football and getting mad for being tackled)
- continues to shoot someone when they are already down (I don't believe in payback but I have seen on many occasions that other people do)
- doesn't follow the safety rules - blind firing, barrel covers, etc. (I saw a bb embedded in a guys face from blind fire)
- had no respect for the newbie - (personal pet peeve of mine - it's totally unnecessary to ignore, talk down to, target, etc. the new people. Without new people the sport will die...)
I say continually for most of them because everyone is human and makes mistakes now and then. I'm sure there are hits that I didn't call. The difference though is that I wasn't aware of it vs. knowing you are hit and continue to play.
Now on to the positive -
That Guy who...
- lent out a speed loader when someone was out
- risk getting shot to drag another to a medic
- gave constructive advise - (one of my favorites)
- respects getting hit no matter who shot them
- mentored the newbies - (another favorite)
- is genuinely nice (who wants to play with someone that's mean?)
Being a newbie I am always up for advise from the experienced players. It is the easiest way for me to learn and is a nice way to socialize when I'm amongst people I don't know. The mentoring runs along the same line - it's helping the new player get acclimated during the game.
My personal preference and I would imagine many others would agree, it's a much nicer experience and atmosphere playing with the positive "that guy".
