It would be an antimeme if the person in the first panel said something like "someone give me a thumbs up"
The distinction is that the bone hurting juice meme takes an element of the meme and transforms it into something else, and an antimeme just over explains it.
Usually the person on the left is saying something negative that the group enjoys. Then one person of the group gives them a dismissive thumbs up and continues their convo. In OP the joke is that the thumbs up kind of looks like a cello, instead of the normal meme layout instead the guy is simply asking for a cello and the group gives him one.
