Stabbing rhinocerous 

When a girl with a giant nose is giving you head and her nose keeps stabbing you in the stomach.

Tom: "Dude why is your crotch so bruised?"
Robert: "Its because Betty gave me head last night and it felt like I was being stabbed."
Tom: "Damn that's gotta hurt, I'm pretty sure that's called a Stabbing Rhinocerous."
Robert: "I can see why."

Snot Rhinocerous 

When you have a cold and you blow your nose in someone's asshole while pinching the head of their penis.

"Hey honey, I'm feeling a bit under the weather, and we're out of tissues. Do you mind if I give you a Snot Rhinocerous?"

"But I don't have a penis."

"Strap on this dildo."
