TELL ME SOMETHING I DON'T KNOW!! (for the texting lions and lionesses) a texting response to someones' 'same old song', expressing boredom (YAWN!!) with someones repetitive and/or boring prattle, you've heard ten thousand times before!!
texting: babble, babble babble...-T.M.S.I.D.K.

that 'bird' is SO excruciatingly FINE!! -T.M.S.I.D.K.

urban dictionary no longer likes michael foolsley definitions!! -T.M.S.I.D.K. !!
