Plastered Mcshitfaced 

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.
