When a guy is getting a blow job and he misses his mark while cumming and it sprays across her upper lip and a little gets in her eye. She then yells "ARGH! ME' EYE!" while squinting the aforementioned eye closed, while the cum mustache drips down either side of her mouth, resembling a wicked pirate's facial hair.
I was giving my BF a hummer and he wanted to cum on my tits, but he misfired and I ended up with a Pirate 'Stache. My eye still stings and since then I keep getting whiffs of bleach.

When you cum on someones upper lip. Sometimes around the holiday but by all means during Santa's off season.
- I gave that dude at the glory hole a mean Santa Stache the other day.
- Why would you tell me that.
-??

"A play on words made in reference to March Madness. March Madness is the annual college basket ball tournament held every year in March to crown the college basket ball champion. I know you don't watch sports so you can't relate BUT real men know exactly what I'm talking about." ~Kyle (pronounced K-aisle!)
Guy 1: Let's grow mustaches for Mustache March.
Guy 2: It's now March Stacheness, because I made it up.
