ESL = English as Second Language, in simpler words: someone who doesn't speak English as their mother tongue. And I guess they couldn't be bothered to write "European" fully so they just wrote euro.

I'm both ESL and European and never gave a single fuck about Cindy, not back when she was posting Sims videos and even less after she stopped posting them in favor of sharing her trainwreck of a life so I don't get why people are interested in her either. Poor woman, her life is a mess but good for her that she can at least turn it into profit via YouTube money I guess.
