I don't like you

There are some strong words out there. Those that hit home most are the negative ones, so if you wish to reference something that you would attribute a negative connotation to this may interest you

Anathema

This is a person or thing that is detested or loathed. Thus, you can have an anathema or anathemas. For instance, one of my personal anathemas is the use of crass language. Anything and everything could be your own personal anathema, making the application of the word near limitless.

So go ahead and loath things if only to give more opportunity to use anathema.
