Choroba = old-fashion English pox on you
BTW choroba is a eupehmism for much stronger cholera.
Psia krew & psia jucha
Jeny kochany (euphemism for Jezus kochany)
Oj rety = euphemism for oj rany (English zounds < God's wounds)
NOTE: Invocaiton of the Deity or Blessed Mother were extmrely strong curses back when so they spawned a series of euphemisms in different in English i.a. gosh (God), good grief (good God), gee whiz (Jesus), cripes (Christ), bloody (by Our Lady) heck (hell), darn (damn)
