I don't know if I simply misinterpreted their words, but somebody implied to me that the word douchebag is not an insult. Not only that, but it can actually be a compliment.
In what world is this possible? This person helpfully explained to me the literal sanitary purpose of a douche bag. I think this person is unaware of it's insulting and figurative use.
But even with the literal definition, how could anyone consider it a compliment? It doesn't make sense. Maybe because it's a sexually invasive object? Would a man want to be a douche bag? I think that requires a rather high level of perverse fetishism.
There's really only one way to interpret being called a douchebag:
You're being insulted.
