I've read of a language, or I guess dialect of English called "European english", i.e. English as spoken Europeans that learnt it as a second language. Another example is how a Brit using too many idioms like "Bob's your uncle" would confuse English speakers that haven't been exposed to Britishisms.

Searching on YouTube just gives me this relevant result, an English that has some new/odd words that's been adapted by the Euro-bureaucrats https://www.youtube.com/watch?v=vf8KxvRYvQU
