The viral achievement was introduced with a bunch (or, at the time all) achievements around Juli 2013(???). It was Heyheuhei who got the achievement first, from there it spread around the community. 
was the first time HHH lost, so at the end of the tourney 4 players had the Viral Achievement .
I'm not sure why HHH was chosen, but someone else should know that...
