A Bea fan insulting someone with their weight? Surely not.

Bea clearly was causing trouble by asking about the butter, David clearly saw it and gave her a tongue lashing.
She then went and tried to use that by pretending to be upset and fake crying.

Hilariously bad acting.

It backfired. She even got nominated for eviction with Marcus. That look of shock on her face. She doesn't get that smart folk hate her.
