Manchester United supporters should never refer to themselves, or the club as “Man U,” because it is derogatory insult towards the club.
The term is only used by supporters of other clubs as a complete and utter insult to our Manchester United. The “U” is meant to be “you” by the rival fans.
An early example of its usage is this chant by West Brom fans: “Duncan Edwards is manure, rotting in his grave, man you are manure – rotting in your grave”. The origin of “Man U” is a song to insult the dead Duncan Edwards.
Liverpool and Leeds fans copied this with their own man you /u versions to insult all of the lads who died at Munich: “Man U, Man U went on a plane Man U, Man U never came back again” and “Man U Never Intended Coming Home” (if you combine the first letter of each word you get the word “MUnich”).
This makes it a lot clearer that saying “Man U” is an insult, particularly to the older supporters and to see United fans using it now is shameful.
If you are a true Manchester United supporter, you will have read this and re-post this so all United fans can spread the word, because … WE ARE MANCHESTER UNITED!
