A quick google would have enlightened you, but "sunny side up" just means eggs fried from one side only, usually with the yolk still being very runny. "Over easy" seems to refer to eggs fried from both sides (hence flipped "over") but with the yolk still being runny (hence "easy", i.e. gently). For the record, I'm a European ESL speaker.
