WACCOE - Short for We Are Champions, Champions of Europe.
Leeds fans think they are chamions of europe, because they are delusional and think they are much better than they actually are.
They can't even win league one, never mind being champions of europe!
Leeds Fan: WACCOE! We Are Champions, Champions of Europe
Any other fan: No your not, you knob jockeys!
Leeds Fan: (insert a number of profanities here, and you won't even be close to how vile a leeds fan is.)
