Jay Leno

To give or to promise to give something then take it back later on.

You gave me that iPod and now you want a back? Your such a Jay Leno.

jay leno

A strap-on attached to the chin, used especially for penetration and party tricks. Similar to a screwnicorn, in which the strap-on is attached to the forehead. It is thus named because the wearer winds up with the ginormous chin, only slightly smaller than that of Jay Leno.

I tried sending a picture of my jay leno in to Late Night as a look-alike for Jay's chin, but they did not show it on air on NBC. That pissed me off.

Jay Leno

Jay Leno is renowned for providing background noise for elderly on nursing homes. His barely understandable speech and crappy jokes help the geriatrics sleep better.

Jay Leno: "Do you like the March Madness? Here's how it works: First you start out with 65, and then one by one, people are sent home until there's only one left, no, I'm sorry, that's our coalition in Iraq."
Elderly: zzzzzzzzz
