What do you call this position and how do you describe it or write in a sentence? Thank you .

Is this the sex ed sub

I don’t have a name for the position but I’d describe it as “the lady jumped into his arms and wrapped her legs and arms around him.”

You might call it a sort of "standing carry." Note this sounds formal, and it does not imply affection towards the person being carried.

back in high school wrestling we called it a suplex

I have no word for this position/experience. She jumped up on him and wrapped her feet around him. They were face to face as he carried her across the room.

It is referred to as "lifted hug".

I call this “koala-ing” but looks like this term is not well known.

Reverse koala?

Does this have a specific name in another language?

I would say she's straddling him while he's standing

"She jumped into his arms and wrapped her (self/legs) around him"

Her legs are wrapped around his waist. For your sentence, one example would be “she jumped into his arms and wrapped her legs around him/his waist.

Game of Roses, a podcast about the Bachelor, calls this a Huju. Hug Jump. It's not widely used for sure, but that exists at least. I guess I mention this to say that there isn't really an immediately easy widespread name for exactly this, since they resort to calling it that. And it happens a lot on the show.

closed guard in bjj So she jumped into a closed guard I'd say maybe 😅

Standing missionary position...

This is colloquially called "Uppy". Ex: I want Uppies [https://en.wiktionary.org/wiki/uppy#English](https://en.wiktionary.org/wiki/uppy#English)
