Passing out Drunk or from downers usually in public and becoming a gelatinous squishy blob on the floor or ground soaking up what ever spilled drinks, piss, dew, rainwater,ect that are in the vicinity are said to be Puddled the fuck out. Can also be used to describe some one getting knocked the hell out.
Most Alcoholics and Fratboys Puddle out from time to time. David Hasselhoff, That dude grabbed my girls tit so I puddled his ass out. I gotta go home I'm Puddling out.
You have massive diarrhea all in your bed leaving a puddle on the mattress and sheets. You then proceed to throw your partner into the puddle and FUCK or have intercourse all in the puddle of "butt mud". Hence, Mud Puddling!
Man my stomach has been sooo upset today. I think I'm going to go home and enjoy a good hour of Mud Puddling with the wife/husband!
