Derpmates 

A variation of the word teammates, a Derpmate is the kind of player you encounter 99% of the time on Xbox Live or Playstation Network while playing first-person shooters. Derpmates are generally poorly skilled at the game, fail to follow directions, and generally just make the game un-playable and not fun, by constantly dying and screwing up while you're trying to get them to do the god damn Shangri-la Easter Egg!

Why Treyarch did you make an Easter Egg that requires four players, then match me up with three Derpmates!!!

decimate 

A frequently misused word.

Decimate literally means to reduce something by a tenth, but many people use it instead to mean "totally destroy." The word "obliterate" would be a better choice than "decimate."

Decimate comes from the root "deci-" which can be found in other words involving ten, "decimal" for example.

When I decimated the cookies I ate ten out of the hundred-cookie batch.

Joe decimated the rock collection by getting rid of one tenth of the rocks.

decimate 

the verb to "decimate" comes from the root of the Latin word for ten. Obvious enough, but the use gets more interesting. The verb "To decimate" is synonymous with "to destroy" and may be used to talk about a great reduction, loss, etc. "Decimation" was used as a Roman military strategy, as punishment for a severe crime, typically rebellion or desertion, the army would be forcibly lined up, and every tenth person would be killed. The form of group punishment based on the number ten is an adequate enough explanation for the origin of the word. Today, the word can be used in a less mathematical context, and still be grammatically correct, though it's still an intense verb.
