Test Sniffles 

The sniffles you get during a test by tilting your head downward and allowing your sinuses to drain out toward your nose (causing a runny nose). This is worsened by allergies or a recent illness. The only known cure for the Test Sniffles are to slump your back and shift your legs foward so that your head stays upright and your eyes peer downward.

I was failing an English test when I realized that suddenly, everyone in the room was sniffling. I quickly jumped out the window and drove home to submit a definition on Urban Dictionary before anyone else. I decided to call this phenomenon "Test Sniffles"

Crotch sniffle 

When you're banging a chick who is embarrassed about how much of a slut she is and she has to excuse herself after the first two thrusts to 'use the bathroom' but she's really just in there trying to flush out her cum pot.

Yeah bro, She had an immediate crotch sniffle and ran to the bathroom, so I considered putting a condom on but I didn't.

glue sniffer 

Someone who does things that are so questionable, and plain out stupid, that they have to be sniffing glue in order for them to even come to that decision.

Harsh and Lusion printed the cannon backwards, and then failed with 12 on. They are glue sniffers.
