"Dormida" is a Portuguese word that means "Sleeping." In the context of a porn video tag, it typically refers to a scene where someone engages in sexual activities with a person who appears to be sleeping. This could involve anything from caressing and touching to full-on intercourse. It's important to note that the person is pretending to sleep or has consented to the act while appearing to be asleep, so there's no question of taking advantage of someone in a vulnerable state.
