Tk 

Tk is that guy that everyone hates and first but if you get to know him, you'll find that he is not such a bad person. He is a smooth talker and plays love games, but does not cheat. He minds his own business usually, but defends his friends in need. You'll find that it's hard for him to commit to a relationship because of his insecurities.

Tk, the motherfucking player

When somone makes a joke, but then it's carried on beyond beleif; to the extent that it's fully and utterly killed.
somone is then at liberty to call a 'TK', and the job is done.

"And then i shagged your mum and she loved it!!"
*silence*
"TK....".
