Text Interjection System almost sounds like the Star Trek version of a name for a simple dialog system in a game, then. It's not like I'm trying to make fun of it or make it sound like a weak addition or something, but I tend to get some amusement out of seeing fancy names for things that aren't fancy. It's like, if someone is in a dire situation, and is actually really monotone about it. The contrast makes it funny to me.
...or maybe it's actually called a text interjection system in technical terms, and I'm just being silly.
Oh right. We're talking about tvtropes?
I am actually clenching my fist and gathering all of my willpower to not click those links.
