The classic joke excuse, that one is as old as the Earth itself man.
A lot of people try to hide the truth, what they really think and feel with jokes but please, backpedal harder! Something like that was weirdly personal for just a "joke" or you guys have a very disturbing sense of humour.
Just fucking weird man. I pity anyone who has to get their kicks off insulting others then claiming it was a "joke".
