I once got in major trouble with my manager for saying 'bloody!' with emphasis. She was english but very prudish. 'Bloody' was shocking and forbidden, but 'sugar!' said with same emphasis absolute fine (and shouted by her regularly).
Very embarrassed (at a meal out) by nice German woman who asked people at the table to explain what 'bugger' meant. Everyone mumbled and wouldn't answer, so she turned to me . . .
On a zoom call, caused hilarity and embarrassment from USAnian colleagues; I had some cardboard boxes behind me. One of them had "Who gives a crap" on the side. 'crap' naughty word, titter, he he.
