I understand that some people have issues with the cult like behaviour of crossfitters and the dodgy ones doing retarded stuff with bad form while fatigued but from the limited experience I've had with crossfitters (mainly at strongman/woman comps), they've all actually had really good form (especially compared to some strongmen!) and have been nice people overall. I don't like to generalise that much to say all crossfitters are douchebags or whatever. You will have good and bad examples of different types of strength athletes across all disciplines.
Pissing yourself is just stupid though!
