Like if some one says "I like red" some one else chimes in with "Pfft! I like blue" the ESTp gets all excited and says "Pwned!" Most of the time it's when some one says something in an unnecessarily aggressive way... and make themselves look bad. Do they say "pwned" so the other person doesn't look so bad, or do they honestly think it's funny? Another ESTp I knew would say "good call" all the time, as if his opinion was superior and respected in things totally unrelated to him.
