Derived from the word decent, dec is another word for awesome. You can add prefixes and sufixes to dec to make it mean better or worse than it is. Dec as hell!!= really fucking awesome. Pretty dec=not to bad.

"dec" has yet another meaning, "don't even care".

This is an offshoot of dek, "don't even know", which is itself an offshoot of idk, and a cousin to idc.

It can be used in many of the same ways as dek, but for certain reasons (they sound the same when spoken), it isn't a good idea to use it as a single word when speaking.
Not dek, dec! D-E-C. I said I D-E-C.
