Definition

A definition of a definition is a stupid oxymoron that has not stopped pissing me off since I started thinking about it and should just die.

If you were to give background to something or give the meaning to a word that would be the definition; so when you define the word definition you create a sentence that contradicts itself, thus questioning yourself if it makes sense, resulting in your brain confusing itself, and furthermore not letting you think about anything logical for the next thirty minutes.
