A phrase put in the title and/or description section of youtube videos by incredibly stupid
people who
don’t understand how copyright laws actually work. The phrase makes no logical sense because it directly contradicts their action of uploading content which they aren't the copyright holder of.
By analogy, according to
people who use the phrase, someone should be able to shoot them in the head while yelling “NO HARM/MURDER/MANSLAUGHTER INTENDED!” and get away with it.
