The expression TIT stands for This Is Thailand and is used for things that are typically Thai. In my serie This Is Thailand (see label) here a simple photo to show how to use a western toilet. Weird? Well actually not as I have seen this at many places.
Lets explain it. Until more and more western people did visit Thailand an squat toilet was the norm in Thailand (and actually everywhere in Asia). But nowadays you will see more and more the western model of toilets. And Thai people who have never been used to this kind of toilets actually do not know how to use them. And instead of sitting on it they will use it the same way as the squat toilet. And then later saying "How stupid that people make toilets like that!".
