Irish mudslide
The act of two sexual partners laying on their backs and placing their butts in the air, then releasing fecal matters onto one another's chest and face.
Ben, the leprechaun, got so drunk last night that he passed out after participating in an Irish mudslide leaving shit and used condoms on his chest and face- TFM.
Irish Mudslide
When you take a shot down someone’s butthole while they simultaneously shit in your mouth.
“I needed to shit at the restaurant and my wife snuck a shot of whiskey into the family bathroom to Irish mudslide that turd”
