Which one should you use?
Depending on the level of formality required, you might choose different words. For a formal or anatomical context, use nádegas. If you want a polite term meaning 'rear' or 'backside', use traseiro.

Additionally, the diminutive bundinha can be used to add a playful or cute touch.
