When you plug one nostril with your finger, and blow out of the other nostril with everything you have, sending a snot projectile out of the nose.
Without tissue, all I could do to clear my nose was to blow a snot rocket.

The resulting visual when a large gooey slimy snot is launched in a magnificent trajectory from ones nostrils due to vociferous laughing, sneezing, or crying. The trajectory has been known to reach an apogee of 3 to 4 feet above the launch site. These are especially delicious when they land on someone or something that has a deep fear of this sort of occurrence.

To preform: hold one nostral closed and blow out of your other nostral hard enough to make the wad of mucus shoot out of your nose .
like the time Jamielee Cedar-Kelly shot a huge snotrocket in the middle of the mall parking lot. She got a little on her shoe, but she just brushed it off and wiped it on the guy standing next to her.

A particle of nasal excrement launched at such high speed as to achieve escape velocity. It may be launched by way of a sneeze, or the "cover one nostril and blow" method.
