 Get the Shetland Ponymug.
Get the Shetland Ponymug. Also called a snot rocket, the act of covering one nostril and blowing forcefully on the other to expel flotsam and jetsam from one's sinus cavity, usally in a public place.  Named for a character in John Steinbeck's "The Red Pony" with a predilection for said disgusting affectation.
I didn't have any kleenex and didn't see anyone down the street, so I launched a red pony on the sidewalk before hopping on the bus.

Get the Prancing Ponymug. The Inside Part at the beginning of a Girls' Ponytail. When a finger is inserted into this it mimics that of a anus and one can feel as though they are fingering a girl's butthole.
