Do you know any hand signs and gestures or words that are universal?

I know the universal hand signal for do you want to go smoke a doobie. Cheers! This post was edited by Nanoose at January 8, 2020 4:37 PM MST

No

The picture in your question is racist...

Note: the above answer was A JOKE


Although the problem of the "OK" sign being co-opted by the White Supremacist right is an issue...

Know? No.

I think some gestures tend to be very widespread, but I don't think any are universal.
Variations of empty-handedness often signify a greeting with the undertone, "I'm here peacefully; I carry no weapon."

I doubt if any languages have any words with universally equal meanings.
Related languages carry similarities in their roots, but the more foreign the language the less similarity.
Linguists agree that the relationship between an object, the word it is called by and what it signifies is arbitrary.
One exception may be the word "ma" for mother. It is thought by some linguists to be fairly close to universal, perhaps because it tends to be one of the first word-like sounds a baby makes.

Thumbs up. 

A hand wave. 

I am surprised no one has mentioned this. We are all adults here, right?
I'm presenting my answer in the spirit of academia and in response to this post...

If you are orange and have a giant fat face and you point, it means universally, that you are stupid and totally without any moral compass whatsoever.  

And you probably just crapped your pants too.
