糟老头子坏得很，我信你个鬼

Meaning

"Wo bu shizi" (我不识字/I can't read) was originally used as a reaction when shown PDA (showing off love). When encountering lovey-dovey content you don't want to see, saying "I can't read" expresses pretending not to understand and self-escaping. Now used for any content you don't want to see.
