The funny thing is that I genuinely don't recall. The phrase 'cheapass gamer' had somehow entered my consciousness because one day I was looking for more info on a rumored blowout sale and did a search for it. After finding to my surpise there was a site by that very name I had no choice but to investigate. After that it was all "You'll never find a worse hive of scum and villainy" but I joined anyway, figuring I was already ahead in the game.
It is possible the phrase is something I just thought of on my own and turned out to be following the line of thought that had lead to the site's creation but that doesn't seem likely as it wasn't the sort of phrasing I was likely to use.
So those subliminal ads during Masterpiece Theater must have worked!
