14. "Now see that gerbil, grab that tube/Shove it up my butt/Let that little rascal nibble on my asshole" - Eminem
Song: "FACK" (2005)
Eminem devoted an entire verse and a coda to the urban legend known as "gerbilling." Having a small rodent bite at your anus doesn't sound enjoyable, let alone if the varmint actually enters your rectum. We shudder just reading those lyrics, and it's even worse when you hear Eminem rapping it in a faux-Cartman accent.
