The latest to do so is Canadian singer/songwriter The Weeknd ... to wish American-Moroccan rapper French Montana a very happy birthday.
Except ... he did so by calling him a "hayawan," which is the Arabic word for animal. In the context of the post - alongside the fact that Arabs animal-call each other so often - it's actually not offensive at all.
"Happy Birthday Hayawaaan"
The Weeknd shared the photo on his Instagram story on Nov. 9, but that doesn't mean screenshots of the greeting was limited to just that one social media platform.
No, Twitter users were definitely all over the moment ... and believe it or not, it became the topic of discussion among many on the micro-blogging platform since.
