It's just not a good answer. I'd be surprised by anyone finding the answer inappropriate or vulgar.
If you look at any number of other accepted answers for riddles, you'll see that each line in the riddle is separately addressed by the best answers. Typically, each line of a riddle is meant to be another clue, rather than several lines being used to make up only one clue.
Also, "square" is a term that has been used in the past as a perjorative, meaning "nerd" or "geek". That's clearly part of the meaning of the first line of the riddle, since the word "nerd" appears, and it has nothing to do with the shape of breasts.
On top of all of that, you have only two real justifications for your answer. One of them makes no sense and the other one doesn't really work with how riddles are typically written.
So in answer to your question, keep the following in mind when answering riddle questions:
- Each line or sentence of a riddle usually adds something separate to the riddle - like a separate clue.
- The best answers address each clue, and therefore each line or sentence separately.
- Most riddles here are either solved very quickly or are pretty subtle. Don't try to justify the first answers you come up with. Instead, attack your own answers and try to figure out how they might not work.
- The best answers to the best riddles will be indisputable and obvious once the answer is known. If your answer doesn't "click" really well with the riddle, it's probably not the best answer (or the riddle is not great).
- If you are not a native English speaker, you are starting at a disadvantage with riddles, since there are often idioms and colloquialisms used in riddles that can be challenging. You may have to work twice as hard on riddle puzzles as you would on other types like Math puzzles.
Here's an example riddle for demonstration purposes (by J.R.R. Tolkein):
No legs sat on one leg
Two legs sat on three legs
Four legs got some
Here's a not very good answer:
No legs sat on one leg
Two legs sat on three legs
Four legs got some
It's a relay race, which is run in "legs". The racers rely on each previous racer so they are "sitting" on each other. The last racer got the prize.
One bad thing about this answer is that "sitting" is not a term used in relay races, even though "legs" is. Also, it doesn't explain how each new line adds something separate to the riddle and its answer.
Here's a better answer (the correct one):
No legs sat on one leg
A fish has no legs. It's resting on a table made from a upended log (one leg).
Two legs sat on three legs
A man (with two legs) is sitting on a three-legged stool next to the table while eating the fish.
Four legs got some
When the man is done, he gives the scraps of fish that he didn't eat to his pet cat or dog (both of which are four-legged animals).
First of all, this answer immediately rings true. The "legs" are literal. And having the pet eat the scraps makes perfect sense with the line "four legs got some".
Second, each separate line and clue is addressed and makes perfect sense.
