É mais ou menos isso. Tem o mesmo significado de "What are you insinuating?"
Ex.: Joe- Hey I noticed your new hairstyle
Becky- Yeah I added the white highlights to my dark hair, thought it would look cool
Joe- Ah, you know skunks kinda have that same look, black hair with white stripes
Becky- What are you getting at? (What are you insinuating?)
