나...오라면오고 가라면 가는 그런 쉬운 남자... 맞아! Looking at the whole phrase grouping the parts: 나(는) [[오라면 오고] [가라면 가는], 그런 쉬운 남자], 맞아! The sentence has -(이)야 (or 이다 - am) omitted. In full, it's 나는 ... 그런 쉬운 남자야, 맞아! (Such omission is common in captions, song lyrics, and newspaper headlines) 오라면 오고 is short for 오라고 하면 오고 (come if you ask me to come), and 가라고 가면 is the same except "go". So the literal translation would be: - I am [[such an easy guy], [who comes if you ask me to come] and [who goes if you ask me to go]], right! Which means: - I am such an easy guy, who you can order around at will, right!
