Curdy is an adjective for your average cute but nerdy, the-boy-next-door type. A boy who is described as curdy may also be called adorkable or geekchic. Curdy is literally the combination of the words cute + nerdy. NOT TO BE CONFUSED WITH THE STUPID SLANG PUURTY. Like when people say pretty with a dumb accent.

Boy 1: You know that girl in our grade? Super smart, really pretty?
Boy 2: Yeah, she's pretty curdy.
