Rail Mooch
Someone that rolls up to a rail that you spent all day going on crazy missions to scope out and set up and then they come at the last second and shred your rail. Or they sit there and watch you set up clamin they are just gonna film and then they decided once its set up to drop in.
Chad just sat there and watched us do all the work setting up the rail and then once it was set up he tried to do the rail but all he did was a front nose slap.
