Nostril-damus 

A person making a very specific prediction - that something you do (such as telling a joke or performing physical comedy) will make your friend(s) spew beverage from their nostrils from laughing.

Friend: Lifts a beer bottle to his mouth.
You: Rip One.
Friend: Becomes a beer fountain, from the nose.
You: "I knew that would happen. Call me Nostril-damus."

the nostrel damus effect

When you do way too much coke. The worst plugged nose ever.

Guy 1: Are you sick?

Guy 2: Naw, it's just the nostrel damus effect.

Nostrildamus 

The act of ejaculating into your partner's mouth during oral sex, followed by tickling her or him (hopefully her, or else you're a gay) so much so that the ejaculate is expelled through the nostrils of the partner in much the same way that milk comes out of your nose when laughing.

I totally pulled a Nostrildamus on Christina Saturday night!

Nostrildamus 

Something you can smell before you see or hear it (e.g., shit, fire, dirty pussy, politicians, etc.) .

James’ inner nostrildamus knew when the pie was ready.

Suzy was such a nostrildamus for finding trouble.
