FEM

FEM is Undertale gamer slang for "Frisk Eradicating Monsters", Another word for the Undertale Genocide Route. Male enthusiasts for the Undertale genocide route are known by the fandom nickname "FEMboys".

History
The slang term "FEMboy" originally originated from ROBLOX after the platform censored the word "Genocide" after the 4chan Conquest of Uganda back in 2018. This move caused major controversy in the Undertale fandom, And caused the phrase "FEM" to be created as a substitute for the phrase "Genocide route"

Relation to Genwunners
FEMboys and Genwunners are close allies, Especially when defending the Undertale and Kanto Region fandoms from various problems. Every year, Grandpa Phil rents out the entirety of his local Hooters restaurant and runs a FEMboy convention where all fans of the Undertale genocide route get together in Undertale cosplay and sing the musical parodies by LHUGUENY
