offense intended

The opposite of "no offense"
It's what you say right before insulting somebody to let him know your insult is intentional and that you mean every word of it too

^ No offense, but you support racist immigration policies, and I don't respect that
> Yeah, well, offense intended: I screw your Salvadoran girlfriend behind your back, and she loves it. So take that, you cuckolded little B
^ Hey, what the hell!
