👉 "D'Aguilar" is a term that comes from the Spanish name "Agua," which means water. It's commonly used to describe someone who's extremely quiet and reserved.
In this context, it might be interpreted as: "You're not even trying, are you?"
An edgy example sentence could be "D'Aguilar was an all-around nice guy, but he couldn't hold a candle to my quirky personality."
