Vertaling - Braziliaans Portugees-Engels - como assim?

I don't think this translation is right, see the comments under the Finland translation

If it's "what do you mean by that", then just "what" should be sufficient.

Yes.
'What?'

But "What?" and "Like what?" are not the same in English. Are they both possible translations of this?

Does it exist: like how?
The person is just asking for an explanation about what the other person said.
Is a pop what do you mean

I changed it to "what?".

I think she could be a little more specific on the next one.
"Com assim?" could be "O que?", much easier to translated (that was pretty hard to find the right meaning for the finnish one)
