Someone who uses trainers in online games and says they are hacking. These people usually memorize every button from the trainer without even having to look at it. Biggest noobs ever, If you see one, shout out "TK!!!!"
Stephen - "Hey man i can hack my level"
Me - "ORLY?"
Stephen - "Yeah man i use t-search"
Me - "bull shit, I know you use trainers! TK!!!"
Random guy - "WHATS A TK?"
Me - "TRAINER KING!!"
