sung when the refs sh*t
You're not fit, You're not fit, You're not fit to referee! You're not fit to referee! (repeat)
Sung against Man United when the ref gave 6 minutes added time
Targeted at Forest fans living on their grandad's team past glory
Sung whilst jumping around swinging arms around frantically like Wenger. Sung at home to Arsenal as Wenger frantically waved his arms around at every single decision.
when some scores a late goal to equalise or to win
Against Wolves after Phillips scored his two goals
