Context: I follow a Japanese artist on Pixiv who posts short original manga periodically. Recently he posted a new chapter of his manga ahead of his posted schedule announced on his Twitter, I read the new chapter and replied "早い！" thought I convey the meaning "wow you posted this early!" I know I could have phrased it better but I was too excited and still quite new in Japanese (N4). The original creator replied to my comment with "即オチ" I then did a little research trying to understand what he meant but I couldn't... Seems like an internet slang. Can anyone explain the meaning of this slang?
即 means "instant" or "immediate". オチ is from 落ちる, and has two major meanings:
- punchline (of a joke), final joke (of a comedy performance), final result (of a story)
- falling in love, being hooked, being addicted
So 即【そく】オチ refers to a type of manga where the funniest part comes near the very beginning, or a manga that is simply very short, or a manga where someone falls in love immediately. Either way, I think the author thought your comment (早い!) referred to the content or length of the manga rather than the post date. Does the posted manga fit this description?
