Loti = Laughing on the inside. Because how many people are really laughing out loud whilst looking at their mobile device? Its more honest at least.
After hearing the joke of the day I was loti so hard I almost lol.
An abbreviation for 'laughing on the inside'. Realistically, we don't go around loling everywhere so why give the impression that we are constantly exasperated from all of our laughing.
