I think it simply says/means digital but pronounced in a Korean way. X3
They modify certain English words to make it sound better and easier to pronounce in their own language. It was the same for Japanese, when I studied it for a short period of time... Like toilet = toire (to-ee-reh). Sorry this is off topic! -_-' I get carried away.
And sorry oNecoOlazN, I'm not Korean... =/ Of course it would make you feel better to speak to other Koreans with the same issues but even if I'm not, I have that problem too, if you need to talk!
