A Barry Nudge came from the man of two first names, the Legendary Jack Barry. A Barry Nudge is derived from giving a bottle of liquor a decent necking which is usually more than 1/3 of a bottle in one sitting.

Craig: Yo Dan! I took an insane, bat-shit amount of Extenze other day and now my dick is as big as my leg!
Dan: Dude, it's like you have a third leg!
