The song "Sentada Mestre" by Jerry Smith & Os Hawaianos is a Brazilian funk song that talks about a person who never wanted to get involved in relationships and only wanted to have casual encounters. They enjoyed the pleasure of being with different partners until they meet someone who changes their perspective on love. The lyrics describe how this "novinha" (a term used to refer to a young woman) arrives in their life and closes their heart. The line "com uma sentada mestre deu uma chave de raba de mim" is a play on words, referring to the sexual act of the woman's "sentada mestre" (a sexual position) and how it made the person fall in love and gave them a "key to their heart." The phrase "deu uma chave de raba de mim" can be roughly translated as "she gave me a key to my heart." It signifies that this person's sexual encounter with the "novinha" had a profound emotional impact on them. Overall, the song portrays a change of heart from someone who was only interested in pleasure to someone who becomes captivated by love due to a significant encounter.
