It literally translates to "shaped like rice," but it carries a deeper meaning in Filipino culture. It refers to someone who is stocky, plump, or chubby, particularly in a cute or endearing way.
So, while there's no single word equivalent, you could use phrases like:
* Chubby
* Plump
* Stocky
* Curvy (if referring to a woman)
* Rounded
Remember that the tone and context are important when describing someone's physique. "Hugis bigas" often carries a positive connotation, suggesting someone is healthy, well-fed, and adorable.
