Whats the rudest you've ever been to someone?

[Gandalf]

I got my car back today and someone was tailgating me so I wound down the window and gave him the middle finger. I also once called a policeman a cunt and got arrested.

I am shocked at your bad behaviour, fancy that why did call him a cunt you should have called him a
fuck in twat that's much better.

I called him a cunt and he said 'say that again' and so I did. The next thing I knew I was in a cell for the night. Freedom of speech, my arse!
