Oxygen Pirate

...is probably the worst insult you could ever say to someone. No not a four-letter word. Calling someone an OP means that you don't think that they deserve to breathe, they're just hijacking other's oxygen needed for aerobic and anaerobic respiration. (I did A-Level Biology, I got science skills). It's even worse than being called a waste of space. Because at least you think they should still be allowed to breathe and exist.

Many people are oxygen pirates. I haven't called anyone that in a while. But I can think of a few examples.

Veiled Insults

When someone describes you as 'interesting' that's just insulting. Interesting is what you say about someone or something WHEN YOU HAVE NOTHING ELSE TO SAY.

Interesting + another comment - that's ok.
Just interesting = not fine.
