Judging by foreign-language TV shows/movies I've watched, here are a few English and/or American-English words / mutterings / phrases that now seem universal, no matter which language you speak:
Of course, the Italian word “ciao” has been universal for years.
And, it's always possible English stole the others from other languages, as we are wont to do.
Any others? I feel like I'm missing at least one obvious one. Leave a comment, below…
