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

jay leno

1. Slang for a pathetic hack.
2. Slang shameless hack.
3. One who appears to trumpet his or her lack of originality.

Terms are derived from the characteristics of popular television program The Tonight Show's host, Jay Leno. It refers to him bribing away talent from their original sources instead of cultivating his own (see John Menendez, formerly of The Howard Stern Show, and That Glasses Guy, formerly from The Daily Show With John Stewart) as well as blatantly stealing comedy bits from other comedy shows (see Celebrity Jeopardy skits, originally performed on the program Saturday Night Live).

"Billy overheard the premise for my Science Fair project and he totally Jay Leno-ed me."

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.
