Whilst pulling your pointer finger out of your nostil, a stretchy, gummy substance sticks to your finger and the inner rim of your nose. Also known as stretchy boogers.

Some string boogers are known to stretch several inches before detaching from the nostril.
I just had an extremely long stringy booger which, to dispose of, I proceeded to wipe under the edge of the table.
