Acronym meaning 'Just Saw This' for use when responding belatedly to a text message. A great time saver as 11 words are thus condensed down to three. Now instead of having to type out 'I'm so sorry, I just saw this' or 'sorry, didn't have my phone', the user can simply begin with 'jst' Granted these excuses are generally bogus, but this powerful little acronym doesn't care. It works equally well in deliberate or in-deliberate cases.
jst. Hope you found someone else to pick you up from the airport.
