Flonase 

The act placing the tip of your member precisely in the nostril of your friend's soon to be girlfriend and "sending in the swimmers". Preferably performed in a public restroom.

I considered giving it to her in the eye, then I decided to go for the flonase

The Flonase 

Right after an explosive orgasm, when the woman is in her dazed and flustered, head back relaxed state of mind, the male places his penis-tip up the girls nostril, and ejaculates.

I was bangin Stacey last night and it was pretty wild. When she came I had to sudden urge to give her The Flonase. We won't be hearing from her anymore.

Midnight Flonase 

The action of being blown and returning the favor by releasing jiz into the females face, causing loss of smell and taste.

My midnight flonase in her face helped clear my g/f's sinus problem.

Chocolate Flonase 

When one presses their rectum up against their partners nasal cavity. Then uses flatulence to clear out the others sinuses.

My sinuses were clogged up. So I got my boyfriend to do a Chocolate Flonase. He pressed his sphincter firmly against my left nostril and whilst holding my breath, he farted in my nasal cavities. Cleared my sinuses and I was able to eat the corn kernels left over.

Flonass 

A brand of Aerosol sprayed in the ass to seal it and thus prevent it from farting. Usually applied forcefully in dark places.

That guy was farting a lot, so I beat him up and put some Flonass in his crack to shut his ass up.
