An extremelylarge penis.
Origin: The words "penis" and "Nile" combined; the Nile river being a long body of water that is worshiped for bringing life to Egypt.
Used to describe an object with structural resemblance to that of a human male's penis. This can connect to sex toys or anything long and skinny, about an inch in diameter.
Anthony: We have a collection of a bunch of... penile things that you guys have sent us in the mail, so Ian's gonna go see if we have any of those, and then we'll just pixelate it in the video, I guess.
