»little boring theory«

when neo is in the car with trinity and switch in m1 and trinity tells him to take off his shirt and he says "what" and switch says "listen coppertop" does she mean that just as an insult or is she calling him that because he is one of the "machine battery" people still and she isn't

and batteries have copper tops.

Yup she's saying that because he's still plugged into the matrix and basically a human batery. Hence the term 'Coppertop' (Duracell anyone?).
