1) sipjiman : typo of sipjima The original meaning of '씹다(sipda)' is 'chewing' or 'bite'. The informal meaning is 'slander' and 'ignore'. 2) maeil : email (EX) Why do you keep ignoring my email? Do not ignore. 왜 내 메일을 계속 씹는 거야? 씹지마(sipjima)!

더 means "more", V + 싶지만 means "want to V, but", 매일 means "every day" or "mail". Side note, you should really learn Hangul. It only takes a few days to get it, you won't have to deal with differing romanizations and you'll get a lot more respect from native speakers when you ask questions.
