That one person in your friend group who acts like your mom. Just kidding, they're a caring and lovable blob of joy. The Grandpappy in your friend group can also be called Gramps or old man\woman. They try very hard to keep everyone happy but they don't take time to make themselves happy. Protect the old Gramps in your friend group becuase you never know when you'll lose em. Luv ya Gramps 👊
