Sinus Infection

The act of sticking your dick up somebodies nose. This can be done as either a prank or to give pleasure to oneself.

I pranked my roommate by giving him a sinus infection. He had a runny nose the next morning.

sinus supremus

Apparently, it is an insult. May have originated in the film E.T. The Extra Testicle.

Greg:"Sinus Supremus!"

Elliot: "Zero charisma!"

E.T.: "Both fags, they are..."

Datarock: "Seen as supremus, you better know she's a genus!"

sinugasm

The exquisite, involuntary sinus reaction to being engulfed in Wasabe or Hot English Mustard. See also sinulate (sinus ejaculate) pronounced syn-u-lut

Things were going OK at the State Dinner until I had a sinugasm over the beef and mustard. When the poor Vice President had to wipe the sinulate off her blouse I thought I was going to pass out!
