✅ Sponge often suggests a pattern of behavior as well as a lack of respect for the person being taken advantage of (She was always sponging $20 from her friends).
✅ Freeload can suggest these things but is often less disparaging (They freeloaded several meals from their grandparents).

✅ Plunge and dive both mean to suddenly become immersed in something or to do something in a way that suggests becoming immersed.
