Some guy with a big chin who is the former host of The Tonight Show, and it appears he'll be stealing the job back. He screwed David Letterman out of the job back in 1992 when Johnny Carson retired, leading to Dave moving over to CBS. He is now about to do the same thing to Conan O'Brien because his own prime time show wasn't too popular with NBC affiliates. He is driving Carson to roll over in his grave.
Jay Leno is a selfish bastard who just can't let go of the spotlight.

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."

When someone retires from a legendary television franchise, passes the torch to a worthy successor. Then he gets bored and starts a new show which sucks and then asks for their old job back by firing the successor.
He's a leno giver
