Recently, the word Avocado has appeared in colloquial speech with a new meaning. My first encounter with this slang was during a trip to Los Angeles. There, in a conversation with young locals, I heard them call someone Avocado. At first I was confused, because it was not about fruit at all. After some digging around in the search engines, it turned out on one of the sites that this word here is used to describe a person who looks great on the outside, but on the inside may be less attractive, like an unripe avocado.

The newer slang use of “avocado” depends heavily on the community or social-media context where it appears, so there isn’t one universal meaning. It’s similar to other viral expressions whose meanings evolve through memes, jokes, and repeated online use. If you’re also wondering what is sybau, that’s another example of internet slang whose meaning is best understood from the context in which people use it.
