"Coldpatch" usually refers to an overweight female. Focal point of a Coldpatch is the area of skin behind the arms. As more weigh is gained, poor blood circulation follows leaving the skin behind the arms cold and patchy.
Guy: Hey bro, that girl over there needs to work out, look at them arms!
A hick town in southern Michigan. Knows best for their corn fields and meth labs. On any given weekend you're sure to find a bunch of coked up local drunks hanging out a shitty bar called 'Sirens' or in the parking lot of a Taco Bell Restaurant. Or the cool thing to really do is walk around Walmart and act cool.
And like its neighbor city in Ohio, the majority of the people born there will remain there for the rest of their lives because to them, Coldwater is the only world worth living in.
