Private school lad. Not a real lad but a lad of sorts. Usually a toned down version of a lad or one who acts like one to be cool.
Must not be mistaken for a real lad.
Person one: "Did you just see that lad over there!"
Person two: "Dude, he's not a lad! He's a Prad, he's wearing a hat and blazer!"
Person three: "Yeah man he's so right he's deffinately a prad."
