Funny how the coach driver could have gotten his message across by using minced oaths instead of the obvious. Back in the day when I was a drill sergeant dealing with trainees, we were NOT allowed to swear at the troops or call them names like maggots, scumbags, etc., so we settled for the following:
ladies
hobos
shitbirds
yardbirds
knuckleheads
slowmo
Elmo
....
Anyone in a leadership position knows that you don't need to call someone a stupid m**&^%f^%$ker to get your message across. It's the effective leaders that can put the fear of god in you just by speaking to you in a nice clear and calm tone.
Unfortunately in this case, these coddled kids are way far gone. They should all be sent to Texas where the school buses don't have seat belts, and the teachers (and perhaps the bus drivers too) all pack guns. LOL
