I've heard this kind of phrase recently.
When your shoelaces come undone and you trip. That.
I'm confused about the use of That. Any comments?

Generally occurs immediately after the description of some scenario:
You know when someone ties your shoestrings together and you trip? That.
Basically, it's short for "I'm talking about that scenario."
I suppose, by the "rules" of elision in English, it can be argued to be "legal" syntax, though it's probably best considered to be "informal".
