Literally a hybrid of (or short for) Shitty Dreads. When a person has those nasty, un-cared for dread locks and doesn't seem to care that they look like a bum.
Dude: "Omg man, check out the Shreads on that guy!"
Friend: "Ohhh hell no, what's he think he looks like?!?!"
Sexy girl who will always ALWAYS be there for you when you need her. Shes stunning and youd be lucky to have her as a friend or even better a girlfriend.
