tree killer

someone who always uses an excessive amount of paper. If they're writing an essay in pen and make a mistake, they ball up the paper and take out a new sheet instead of just crossing it out. If they're drawing something and they mess up, they take out a new sheet instead of just using the eraser. You get the idea. The opposite of a tree killer would be a tree hugger, one who is very frugal in their paper usage.

Just imagine this: if your teacher gives 10 papers a week to each student and there's 20 students in your class, that's 10 papers x 20 students x 7 class periods x 36 weeks of school. That's 50,400 papers used by that 1 teacher every school year. What a tree killer!

cop killers

"Cop killers" are a type of bullet that can penetrate a police officer's body armor -- for example, a Kevlar vest. Cop-killer bullets have a stronger casing and a smaller bursting charge than regular bullets. Regular bullets are made of lead, which is considered a soft metal. Cop-killer bullets are made from stronger metals such as brass, steel, beryllium copper and iron. Cop-killer bullets are illegal for civilians to own, use or sell in most countries, including the United States and Canada.

The 38-year-old police officer was shot and killed with cop-killer bullets, better known on the street as cop killers. Authorities do not know how the suspect in the murder obtained the illegal ammunition.

Killed it

Reference to Axe's double pits to chesty

To "kill" something you need to do it very well. After accomplishing something with great efficiency you are recommended to pump your fist to show people around you that you "killed it" also to signal people from a far distance that you killed it.

After getting test back with A+ "Killed it" *pumps fist*

Cooter Killer

When you are porking your girlfriend, you being on top her on the bottom, and you feel that special feeling like you have to blow a massive load. You quickly but skillfully go into a full fledged handstand and scream any word of your choice. We suggest; "Wooooo" or, "Hi-Yah!". Then as you are coming down, try your damnedest to get it back where you started. The success rate is very poor, but some manage to hit the love mitten. (95% miss, don't feel bad.) Finally, you kill the coot! Thus, the name being...DUN DUN DUN....The Cooter Killer.

CoReSaZ: With those free Trojans I got in the mail, man, I totally gave Fran the Cooter Killer!
B-Dizz: Right on!...Who in the hell is Fran?!
CoReSaZ: Sams mom :)...I wish :(
