Actually there are rules...not hatin' just statin'
In before X can only be used as the first reply to a thread or comment, and only if that thread or comment is bait: that is, there is a near 100% chance that someone else will reply to the OP using a particular meme, flame, or solution. Saying “in before X”, where X is the anticipated response in question (or a variation thereof), under any other circumstances is wrong.
Its not really a rule, considering there is nothing enforcing it. Know your meme is just as immature as the comment I responded to. If anything its an opinion (can't think of a better word to describe it). A rule indicates that it is something everyone needs to follow or there will be responding consequences. Saying "inb4" as an OP does not have a direct consequence. People, such as this guy^ may not like it, but they have no authority over OP, therefore cannot tell them what or how to post.
If it was a question of etiquette, that would be different, but as the previous commenter stated it as "OP can't inb4 you faggot", implying OP broke a direct penalty. That's all I'm saying.
That's true. But wouldn't that make all the rules of the internet not true too. (With the exception of 1 & 2. because that does have direct consequences.) This is ******* with my mind. Everything I know is a lie.
The joke is just that the coroner replied to the detective's question of what the murder weapon may have looked like by drawing on the dead body in front of him, which is pretty unprofessional.
