Gachigire combines Japanese slang for seriously furious with Nanamin, the nickname Yuji Itadori gives Kento Nanami in Jujutsu Kaisen. Gege Akutami's manga began in 2018 and the anime adaptation followed in 2020, introducing Nanami as a former salaryman turned stoic grade one sorcerer. Because the character is famous for staying controlled, clips of him raising his voice spread among anime fans as an extreme reaction. The contrast keeps it popular for memes about patience running out.
