The lyrics combine a dance-floor invitation with an intense declaration of attraction. The speaker says he feels happy and almost overwhelmed when he looks at the woman, and insists that she is the person he needs. The repeated commands to dance keep the mood energetic and playful, while the romantic lines make the song sound more personally eager.
โGet downโ most naturally means to dance here, especially because it is paired with moving around. Calling the woman โmy ecstasyโ is figurative: he presents her as a source of extreme pleasure or excitement, not literally a substance. โYou drive me crazyโ is also an idiom expressing powerful attraction, rather than a claim that she is making him mentally ill. The repeated dance phrases and the brief spoken section give the song the feel of a performance aimed at an audience as well as one person.
The speaker sounds confident when he says he will make her his, but he also asks whether she feels the same and describes his heart as crying out for her. That creates a small tension between boldness and longing. The lyrics do not tell us whether the attraction is mutual or whether this is a serious relationship; they may be expressing sincere romantic desire, playful flirtation, or both.
