Open Question: am i in a mcdojo????????????

hello, not sure if this is an effecive training technique or just plain stupid. i train in karate, and my teacher is says he all about foucus. he does stuff to try to distract us wile we go through our techniques. he says if we can perform them through the disractions itll make our mental more stronger.. wile where sparring or perforing our techniques hell be shouting things like “butt pimples”,”hairs asscheaks”‘ sweaty balls” ect..if we laugh or lose focus we must do pushups or sittups.. . is this necisary? i kno he wants us to focus but couldnt he find another way to try and distract us??
