The act of being so shit faced that your face contorts into something resembling a fish, usually coupled together with losing the ability to open one's eyes.
Marcus was so floundered last night he fucked an Indian girl. Most likely because he couldn't open his eyes to see how hideous she was.
Damn nigga! You got floundered!
Josh took hours.e what he thought was a bitch until she pulled out her penis, then Joe popped out of the closet and yelled damn nigga! You got floundered!
Similar to the Alaskan Flounder Basket act, in this case a warm object such as a wet towel or a heating pad is put inside an un-douched vagina and then is removed and oral debaucheries are performed using said object.
