(verb) to stop what you are doing, cease (This is a military term derived from the command “at-ease” which, even though sounds like it should mean “to relax”, actually is more
restrictive than when a
soldier is at “rest”, where a soldier is free to move, talk, smoke, etc. It is from this point that it is used to bring a soldier under control, particularly if the soldier in question is involved in
grab-ass.)
