While making plans for Grumble to visit the US last spring I told him we'd go to a baseball game. (His first ever.) I told him we'd root for the Paw. Red Sox to win.

My use of 'root' meant: to noisily applaud or encourage a contestant or team : CHEER

I soon learned that in Australia it means: Root (verb and noun) : synonym for f*ck in nearly all its senses: "I feel rooted"; "this washing machine is rooted"; "(s)he's a good root". A very useful word in fairly polite company.

Slightly different I'd say.
