Women men girls love meet die.
The sentence is perfectly grammatical. Here it is with the grammatically omisible pronouns inserted:
- Women whom men that girls love meet die.
It might be easier to parse with a determiner and a comma:
- Any women whom men that girls love meet, die.
It can be glossed like this:
- If men loved by girls meet women, the women die.
However, as the author of the sentence is exemplifying, it is incredibly difficult to mentally parse this sentence, even though it is very short.
