AITA for getting mad at my parents for inviting their friends over to my house without my permission then making them leave?

In the sense that you didn't give them time to make the friends leave a bit more gracefully before threatening them with eviction, Wich seems a bit extreme to me. Now, I am not saying you're wrong in wanting the visitors out, but like I said, they were already there, so the bum rush would not improve risk. Even if you didn't yell, it was rude. But they also have reacted terribly and their friends were dumb to go in the first place, hence the ESH. Now it is what it is, and some peace offering would get things normal again. (Not to the dumb friends, but mom and dad can get a little pass if they were otherwise decent guests?). You know better how your relationship with them is, I am just answering your question.
