UK vs USA, a different language ?

We all know that there are differences between the English language in the UK and in the USA.
Here are some examples :

USA                                             UK
trunk                                             boot
hood                                             bonnet
counter clockwise                         anti clockwise
shut up                                          belt up

In the fly fishing world you will find hundreds of terms and acronyms that in many cases are the same on a global level. But funny enough, even in the English language, there are differences depending on who you are talking to.

I am told that in the UK they typically use the word Sedge while in the US they would use the word Caddis, both talking about the same fly. Does anyone have more examples of typical fly fish terms that are different depending on location ?
