The trend that has arisen in hardcore/metalcore music in recent years where it is only be acceptable for band members to stand/pose in certain ways and to mosh in certain ways so that they may all be in unison. Involves planning ahead and practicing how to move on stage when performing "hardcore" music, ie choreography. Admittedly, sometimes pleasing to the eyes, but so, sooooo wrong and against the true meaning of hardcore music.

Fellow 2: Eh, no! I'm not into fucking hardchoreography ...
Fellow 1: Yeah I know, me neither, but I just picked up some tomatoes...
