Pete went to town and got absolutely Petered last night.
Soaking a tampon in vodka or other hard alcohol and inserting into your pussy in order to get plastered, aka drunk. Perfect for high school dances or when being breathalyzed.
"Holy hell! I got pussy plastered and passed the breathalyzer test! Let's grind on Mr. Tobin!"
When someone exceeds one's own toxicity level on st. patty's day, during the "plastered mcshitfaced" stage it's rumored that one sees leprechauns and a pot of gold as well as a speaking with an Irish brogue.
I was so plastered mcshitfaced I could have sworn I saw two leprechauns doing anal on a pot of gold.
