Which Sport?  Which event?  When is it? 

2010/11 Ashes

I find it hilarious when Cricketers and Cricket followers start ribbing each other.  England against Australia is one of the best sporting rivalries and Oz versus The Poms at cricket is one of my favorites.

Whether you would choose the Green and Canary Yellow or the Blueish Red add your sloganism or combination of, for instance, your nickname plus sloganism and rib them gently.
