He is such a frikin' whacker!

Get the whacker mug.
Someone who has an extensive amount of emergency lights, police equipment, and antennas, legal or illegal, on their personally owned vehicle. This person typically has several excuses to justify their “equipment” usage or installation, and often try to find reasons to use them. Whackers normally get extremely hostile when confronted about their lights. The average whacker is a 16-30 year old scrawny or overweight male, who is in some sort of community safety club, like a police explorer or neighborhood watch. Most whackers have the lights because they enjoy the power trip they get when they are perceived to be a police officer. Most, if not all whackers suffer from severe superiority complex issues, as they lack any sort of power in their job or personal life.
Guy 1: “Todd just bought amber visor lights for his Crown Victoria
Guy 2: “He did? He just bought 6 fake antennas for the car yesterday”
Both: “what a whacker”

Geeky person who longs to be a police officer or anyone of authority or importance. Usually has a car with antennas and lights with no authority to do anything. May have a police scanner hanging from his/her belt.
The Crown Victoria with the antennas and lights belongs to a whacker who lives down the block.

Look at those whackers. They have nothing better to do than pretend their some great person.

Anyone who amasses a collection of amber or white flashing strobe lights for their vehicle so they can pretend they are important. This may also be accompanied by an antenna or black rims. Whackers are a problem because they dilute the already fragile emergency signal, which is used to serve communities by police, and fire/rescue services.
Stupid Whore "Danny is that the police, shouldn't we pull over."
Me "Nah, is just a whacker, I'll throw on my red strobes from the VFD and scare him off. Then give me a BJ."
Stupid Whore "Alright!!"
