In my experience on RRB, we are just like a bunch of guys sitting around our garages sharing stories and occasionally ribbing each other with sarcastic jokes or jabs. Sarcasm doesn't always translate well on a keyboard unless you specifically say that it is sarcasm or add a bunch of smilies and such, and then it sorta loses the whole point of sarcasm. On rare occasions there are people that are just buttholes, but I really haven't seen that here in quite a while. My guess is that someone attempted to make a fun ..., and it didn't translate well through the keyboard.
Build cool bikes and have fun.
