Ali did say "guys c'mon" addressing them all, but seemed to take umbrage with Marcello making faces as if she was being difficult because she didn't want to hear about his masturbation - I don't think she was blaming him for the topic as such, just his response to her objecting to the topic.

Aside from this, it seems plainly obvious following comments from Daze in her interview that Marcello's crude comments are becoming more and more frequent, despite us not having seen them for a while, and so this was probably the last straw for her.
