Man U complain about ABUS ,how come Chelsea fans don't complain about ABCS?

[undercoverbluese]

man u fans regularly complain about ABUS. but recently there has been much more anti Chelsea on here. How come Chelsea fans seem to ignore it?
alicia: man u fans call anyone who says anything about their team an ABU
any one but utd
therefore should chelsea be ABC
anyone but chelsea?
