2. A phrase basically telling the host of Jeopardy to suck it. In similar meaning used everyday to tell someone who seemingly knows all the answers (or thinks they do) to suck it.
Just like saying..Screw you guy! or Fuck off you!
Only in a funnier reference to the Jepardy host.
Its just a big HAHA to the person you are talking to.
Lexi makes fun of Matt saying 'haha my pants dont have white spots'
Matt replies 'oh well, im going to start a trend, so "Suck it Trebek"!'
