nittwad
Nittwad is used to describe a guy who thinks he's super fly with loads of swag. Short-form for "John". Nittwads are swagless and usually say lame phrases such as "aw shucks!", "fudge nuggets!", and "dinkleburg." It is highly recommended that we take precaution of nittwads.
"Do you know that guy named John? He's such a nittwad."
