this is one of the many tone indicators used predominantly on twitter (though some
people also use them in regular online messaging). it means “teasing,” and you put it at the end of a sentence to indicate your
words were meant in a teasing way, and to not take them too seriously. it’s similar to /pos (positive) and /gen (genuine), which are also
common indicators on twitter.
person A: do you wash your
ass?
person B: that should’ve stayed in the
dm’s bro... /t
person A: JSHSHDH SORRY
person B: its ok its ok i was just teasing.
see the /t?
