It means hardworking, which also means you like cooking/baking/or lazily binging. These characteristics are close to the greek mythological creature, gryphon, or griffin. I learned this from my parents, when i asked them what my name meant. I thought it was very un-usual and weird, guess i’m a griffin!
What a hardworking griffin! Griffins are hardworking, so the name “Sainu” means hardworking, as said. So the person probably means, “What a hard working Sainu!”
