Recent event’s make me feel the need to clarify.
Personally, the term “bones” is not aimed to be an insult. It is simply an abbreviation as to being able to see them. Clearly, the heavier you are, the less bone is able to be seen. First it’s the hip bones, then the clavicles, then the rips. It was intended to be synonym for skinny, no harm was meant by the name.
