slop is not, by definition, AI generated. The word slop is from the mid 16th century, and its modern colloquial/meme use originated in 4chan in 2016. That's why we call AI slop "AI slop", and not just "slop".

Time to update your dictionary -

slop: "digital content of low quality that is produced usually in quantity by means of artificial intelligence"

It is strictly this meaning I intended.
