This poor dude. First he started a grassroots campaign to support the conservative tea bagging movement, only to discover "tea bagging" meant something vastly different than what he expected.
Then he signed on to support NOM (the National Organization for Marriage), the group behind the "gathering gay storm" video. They launched a campaign called "2M4M" aka two million for marriage. On the Interweb this too has other connotations as the video's creator notes on his YouTube page:
If "m4m" is "man looking for a man, "2m4m" is "two men looking for a man." It could, however, also refer to a man looking for another man twice. Or two men times four men.
