"Oi cor blimey you lads up for a bit of rounders before tea time?" You fucking posh poncey little fancy lads, go rebel against your parents running through the wheat and reenact A Field in England. You Br*ts probably call that shit "wheaties" or some shit.
Rounders is a different game. We have Cricket instead of Baseball, a gentleman's game that lasts for a week and has scheduled breaks for lunch and afternoon tea.
We refer to Baseball as "silly boy rounders"
