To play wildly or recklessly. A player is said to be "on tilt" if he is not playing his best, playing too many hands, trying wild bluffs, raising with bad hands, etc.
Typically someone goes "on tilt" after something major happens: You make a horrible call, someone makes a bad call and catches up, you lose a lot of money, you win a lot of money, someone talks trash to you and "puts you on tilt" because of your emotions towards what they've said...
Maybe there should be a "Poker Terms" tab up there ^^ somewhere... and we could add "Ben'ed" to it
