Butters is in fact a term for an unattractive woman.. it comes from the phrase 'yeah her body is fine BUT HER FACE!!' which was shortened to butter face and then to 'butters'. Now obviously this doesn't apply to Nil Putters as he is not a woman (as far as I'm aware) and I'm sure he has a lovely face.... but I hope a little artistic lisence is allowed. What else rhymes with Putters?
Okay.. shutters, tutters, flutters.. etc but do they have the same kind of street cred? NO! no is the answer..damn you!!
