Bust A Move is often used to impress another Sim your Sim or townie wants to get involved with. This happened when the first uncle did this and then he and the niece got the bolts to like each other and became interested in each other. Food fight is also a romantic interaction though most that, but can be used to make others not interested to be interested. Sims autonomusly use bust a move as a way to impress to get another Sim to like them in a romantic way. No matter what the wiki says, which is sometimes wrong.
