Wow, what an incredibly Internet-cloistered thing to say. No, this absolutely in no way neared coming from Reddit. I'm sure it predated reddit by at least 100 years.
Edited to add: I know it's kind of pithy to respond with just a link, but that's really all there is to it. Like "a gentleman and a scholar" or "full of win", it's just a phrase that someone typed out of hyperbole, and people latched onto it, turning it into a meme.
You want me to pluck the very first instance a sentence was written on Reddit? I don't know the exact date. I was around and watched it and many other phrases and memes organically appear and then disappear.
It's like asking for an etymology for the word "bat" and expecting an exact date of first usage.
