Week 4 — Mommy Must Murder
Week 4 introduces Mommy Mearest, Girlfriend's mother and a pop-star diva. The entire battle takes place on the roof of a speeding limousine driving through the city at night. This week is famous for containing M.I.L.F, widely considered one of the hardest songs in the base game.
Stage
The stage takes place atop a long black limousine speeding through a city highway at night. City lights streak by in the background, and the limo has backup dancers on either side. Occasionally, passing cars run over the background dancers in a darkly comedic detail. Girlfriend rides on the car roof between BF and her mother.

M.I.L.F — The Skill Check
"M.I.L.F" deserves special mention as one of the defining challenges of Friday Night Funkin'. On Hard difficulty, it features a notorious mid-song section with incredibly dense, rapid-fire note patterns that require precise finger dexterity and timing. This section has become a benchmark in the FNF community — successfully completing M.I.L.F on Hard is considered proof of genuine skill at the game.
Many new players hit their first real "wall" at M.I.L.F on Hard. Practice in Free Play mode and focus on the rapid sections specifically.
