After a night of HEAVY drinking and passing out in a very strange position
man 1: he was do drunk he fell back off his chair with his head on the floor and his ass still onthe seat
man 2: like irish yoga?
when after a long night of drinking, you find yourself slumped over, in a ball, leaning over a table, facedown in a pile of mud, or doing anything resembling a popular yoga pose.
"man did you see him last night? he got soooo crazy, hes so good at irish yoga"
