In much the same way the same way that Clymer became synonymous for the epithet with which it was associated by Dick Cheney, the name McGinniss should become synonymous for pervert. I wouldnt even call him a stalker. Stalking is an activity in which he is currently engaged. To stalk is a verb. The proper noun (or synonym) for a McGinniss is a pervert (or degenerate or any other noun that describes the person). Why put a limit on the descriptive noun for this creep that makes him seem less harmless? No one has really looked into his background to see what lurks there. But underneath a sewer cap, one generally finds.....a sewer.
In fact, I think it would be an interesting contest to see how many different nouns exist in the English language that are synonymous with a McGinniss.
I googled Joe McGinnissstalker and Joe McGinisspervert and got 35,800 and 1620 hits, respectively. Googling Roman Polanski with the same words, I got 18,200 and 107,000 respectively. I think it is time for a McGinniss Surge on the internet to overtake and displace Polanski as the reigning pervert of the Western world.
