Conceived one evening (In July of 2006) out of boredom and laziness, the term 'nasty unicorn' was first used by Joshua Mosley to describe his feelings towards a wet napkin. When the napkin in question was thrown on his face, he told the assailant, "You need to quit with your nasty unicorn!" The term has been frequently used throughout Treutlen County since then.
Can be used acronymns, i.e.;
STNUU- Shut the Nasty Unicorn up
WTU- what the unicorn?!
"Quit with your nasty unicorn!"
