There are lots of English words that have different meanings between American and British, and even some that are different from other regions within the U.S.

crackers:
Maine = tool to break open shellfish (crabs, lobster)
Texas = saltines

bum:
U.S. = hobo, vagrant.
U.K. = one's "posterior"

hood (of a car):
U.S. = in front over the engine
U.K. = Sometimes the trunk lid, engine cover is always the bonnet.

supper:
Northern U.S. = evening meal
Southern U.S. = midday meal; dinner is the evening meal

And then the foreign terms that are adopted into English change their common meanings over time too, and vice versa.
