That’s the catch phrase — the "Where’s The Beef" if you will — of 2007.

The Phoenix has a list of other catch phrases of the year, and when/how to use them.

Here’s the entry for the aforementioned DTMB:

CATCH PHRASE “Don’t Tase me, bro!”
ORIGINAL CONTEXT “By the time 2008 rolls around,” wrote our own Adam Reilly in September, “ ‘Don’t Tase me, bro!’ will have made ‘Where’s the beef?’ look downright timeless.” How wrong can an eagle-eyed and otherwise-faultless media correspondent be? Campus robo-cops may have given University of Florida student Andrew Meyer no quarter when he disrupted a speech by John “Mussolini” Kerry, but a grateful nation took him to its heart. Meyer’s blubbered and futile cry for mercy reaches out Job-like from the core of the human condition: who among us, threatened with the imminent application of reality’s mega-voltage zap gun, has not thought or uttered something similar?
USE IN EVERYDAY LIFE AS a retort to any perceived attempt to intimidate or apply pressure of an authoritarian nature.
EXAMPLE “Hey, this is a disabled parking space! You’re not disabled!”
“Don’t Tase me, bro.”
