Just you wait until we get to the intestine
That real shit, Ms. Frizz kind of life lesson
Magic School Bus type riding on the record

from Asher Roth – Muddy Swim Trunks Lyrics on Rap Genius

Meaning

In the book series/TV show The Magic School Bus, Ms. Frizzle and her elementary school class ride the titular bus on class trips that give them excellent learning experiences and life lessons

For example, if the class was learning about the digestive system, they would magically shrink the bus and themselves and travel inside a living human’s intestines, where they would literally see “real shit”
