dad vibes
When a guy smells like old socks and regret, and you know he’s a dad just by looking at him. He might be your teacher or a guy who eats cereal for dinner.
My math teacher has dad vibes. He even wears a bathrobe to class.
That guy at the park with a lumpy beard and a soda is definitely a dad.
My uncle has dad vibes. He tried to teach me how to ride a bike and failed.
