How do you say you mad cow in Spanish?

Answer 1

The question is ambiguous.

Do you mean:

'(I) don't have a cowman' or '(I) don't have a cow, man'

Or, as an imperative/suggestion:

'Don't (you) have a cowman!' or 'Don't (you) have a cow, man!'

Clarify the question, and a translation is possible.

Answer 2
