@Pat_Walrond "Trooper" as in soldier. As in one who "soldiers on". Being a "real trooper" is to be tenacious and to never give up. A fighter.
I'll be honest, I have never until today seen it spelled "trouper".
@hallmarc
Also, oops! Wrong thread. Sorry everyone!
@hallmarc
@stueytheround This is the best explanation I found. Personally, I've always used trouper.
@hallmarc
The best answer is "trouper," meaning a member of a troupe, or company of performers, that recognize that "the show must go on" despite adversity. A "trooper" is properly defined as a state police officer, cavalry soldier or paratrooper.
