Is this phrase an insult or jealousy?


> 図体ばっかりでかくなりやがって

The person who says it is short but he's also very rude. The people he's
talking to just worked out, so I don't know if he meant `only their bodies
grew but their brain didn't`, or if it means something like `ugh you got so
big` (I didn't).




As I said in a comment I think looking at the [usage and meaning of
やがる](https://www.nihongomaster.com/dictionary/entry/1172/yagaru) could help.
It is a suffix of the verb which indicates hatred and contempt, or disdain for
another's action. In case you already knew this, forgive me for pointing it
out. Could still help others understand though.

Anyway, this gives a clear indication of the speaker's feelings towards what's
happening. Therefore, I would say it's more of an insult than jealousy.
Obviously though, an insult could be generated by jealousy as well, but that
depends on the context. The bottom line is, what this guy means is: _you are
just getting bigger physically!_ (Or more literally: _nothing else but your
body is getting bigger_ ). And the nuance of disdain/insult is given as I
mentioned by the use of やがる as suffix to でかくなる.

**PS.** Let me add one thing in case it's not clear. The "insult" here is not
underlined by やがる. This suffix only indicates disdain for something, not
necessarily an insult. See this example from the link I provided:

> 昔はペチャパイだったのに、いつの間にかこんなに大きくなりやがって。 She used to be flat-chested - just when
> did she get so large?

The insult nuance is highlighted by the combination of that with (図体)ばっかり,
which, as you mentioned, means _nothing else_ but your body is getting big
(probably implying the brain is still small). This combined with the disdain
given by やがる suggests it is an insult. I mean, if there was no ばっかり, it might
simply be that the speaker does not like that the other guy got so big (as in
the example above), not necessarily insulting him for this.
