Mrs. Glover ma'am, your son is so advanced
But he's acting up in class and keeps peeing in his pants
And I just wanna fit in, but nobody was helping me out
When Donald was younger he was a very bright, smart young man, but his teachers would get mad at him for acting out. He wasn’t a bad kid; he just wanted to fit but no one would help him. This can also refer to a line in the Adam Sandler movie Billy Madison.
All the cool kids pee their pants
Also note the in/out wordplay.
It bears some resemblance to a Nas line from “Bridging the Gap”.
