A slimy, viscous string of nose cheese, the consistency of craft glue or thick maple syrup, that has a pleasantly elastic quality to it, allowing you to bounce it up and down from the end of your finger like a yo-yo. Best experienced only with close friends and family, not suitable for parties or somber gatherings.
This cold has me knocked out, but at least I got some good snot yo-yos to show for it.
