(consisting of three sickle-shaped F's)

From the animation "Idiot, Test, Call Animals"

The full name is "FFF Group of Heresy Court", originally from the animation "Idiot, Test, Call Animals". It is a group with the goal of "burning heresy-heterosexuality", with various forms and funny ways. When attacking the couple, FFF always attacks men, but never women. Although the members also aimed at making girlfriends, they never succeeded, which further aroused their anger. The main slogan is "burn!" . FFF Group and its related terms have become common words in ACG circles, and some popular words such as "I'll make gasoline", "We have traitors" and "Barbecue Festival" (Valentine's Day) have also been extended.
