No one at matches really gives a shit...More people say "come on reds" than "come on United" in the Stretty and Scoreboard anyway. Which you rarely see on these boards because the internet isn't made up at large by the same type of people who go to matches.And you use the term 'Man Utd' at these "matches" you go to?
Which is another reason why this rumour has built up I think. The kind of person who would use the phrase "Go Go Man Utd!" is the kind of person that would buy into this hook line and sinker....it's a thing to feel proud about knowing, it makes you think you're in an elite (ish) club of people who know this serious thing linked to our history...It makes you a better fan in your head. Hence why it's often used as a sort of one upmanship.
It's sole purpose seems to be to tell other fans off for saying it.
