Also known as: 弱みを握られている
A Meme that was started on Twitter by the artist Sukezaemon (Stainless Night) in late April 2015, it generally consists of posting a single image of a female character with the caption "僕はこの子に逆らうことが出来ない。弱みを握られている…", which is most commonly translated as "I cannot go against this girl. She holds my weakness...".
