Pinocchio

Used affectionately, often by adults addressing a child who is being mischievous. The tone is warm rather than harsh, signaling mild, playful disapproval.

Calling a person a 'mina' (mine) signals they are being viewed purely as a source of income. The expression highlights cynical exploitation and is non-compositional when applied to a person rather than a literal mine.

Although the individual words are transparent, portarse as a reflexive verb meaning 'to behave' is a common fixed usage that learners often mis-map. The reflexive construction is essential to the meaning and cannot be swapped for comportarse in all registers without a change in tone.
