I go every weekend & typically see some type of interesting behavior, ha.
There's always the 1 or 2 newcomers that shoot themselves in the foot, or spill their paint EVERYWHERE!
The ones that keep shooting their gun not knowing there's no paint left.
The ones that stay back while other team members rush to the other side, and not knowing its their team, they friendly fire.
BUT! The funniest thing I have seen was when a group of 8 guys came in, only played like once or twice, but they all wanted to be on the same team, and go against the people who are regulars at the field. That was a big mistake, cause they got slaughtered.
I also enjoy being doubted, haha. Most of the time it is about 20 guys and 1 girl at the field, me, and when the newcomers play, they don't really expect much from me, however, I always prove them wrong.
