My name is Purple Loving Barney. Am I a meme? (Uh, what exactly is a meme?)

Barney thought this was worth mentioning said

So, I must admit that I have not been following the forum talk, during the past few months, as closely as I once did. My mom's declining health, her breaking her hip, followed by her stroke, and my own doctors and their obsession with trying to figure out what makes me tick (or not tick), has caused me to neglect my purple loving duties at times.

Anyway, today I was watching the LabStream Finale (yes, I know I am partly responsible for the decline and fall of LabStream. Sorry.) and @dashcloud asked them about memes. My name was mentioned.

Give it to me straight, I can accept the truth. Am I a meme?
