As with "Chinese Fire drill" (referring to disorganised and chaotic efforts) the problem is that it's racist. Not like mid-20th century US "People who look different are the enemy" level racist, but it's still objectionable.

So we should avoid doing this, "Telephone" is a perfectly good name for this idea, and it's not racist. There are lots of small changes we can make, which make the world slightly better for everybody.
