this may sound rather wrong and offencive, if you have a small penis. but a Zangerdoodle is not a dick. it is when you are sitting there randomly and you get a boner, and your pants are tight at the middle lower area because you have sat down for a while and the chair lifted the fabric. it starts to hurt your penis as it bends back the wrong way. you have two choices let your little friend suffer, or fidgit in your pants to move it. ( I advise moving it, you dont want any permanent damage).
Zipperdoodle is a doodle on your zipper dont you know? the bird bird bird bird is the word! nah but really. Zipperdoodle is a doodle, aka drawing, on the zipper of pants/jackets/pockets/zippers! usually these "zipperdoodles" are the company logo
