Extra details inserted into a sentence (spoken or written). Usually the details are just relevant enough to be included, even though everything would be perfectly clear (though possibly less interesting) without them.
Everything in (parethesis) is a parenthetical, for example: "I have no regrets, thank God (and praise Satan)."

Get the Parenthetical mug.
someone who litters his writing with parenthetical information (information inside parentheses, be it a side note, background info, or explanation much like this one)
I hate when writers provide us with their each and every thought in parenthetical form, to the extent that the inner-parentheses word count is higher than the actual text! Parenthetical whores!

Get the parenthetical whore mug.
