STIFO

Soutien Total et Inconditionnel aux Forces de l'Ordres.

French saying over-used by right-wing politicians to express their support to the police. The stupidity of the context in which it is often used has made it popular among French political meme pages. STIFO is the evident antonym of ACAB.

Nan mais tu vois j'étais grave ACAB parce que fuck le système tu voiiis, mais là les flics ont finalement virés les SDFs en bas de chez moi donc tu vois, STIFO en vrai
