dec
"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.
