Crotchquake is what's caused for the viewer when a person moves crotch-first into a video camera, causing the video camera to shake.
Bruce Springsteen caused a crotchquake for the entire viewing audience of Superbowl XLIII, by sliding on his knees across the stage into a camera during his halftime show.
