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.
