Famous battlecry from Roy Larner delivered right before he charged down three armed terrorists single-handedly, saving dozens of lives by holding them up. The quote is now used whenever someone performs an action that the majority of people wouldn't dare do, whether it's a selfless and heroic act or an act of breaking the rules. "Fuck you, I'm Millwall" basically means you're about to go against the flow, doing what you feel is right even when others would think doing so is madness, as any Millwall fan would do.
"Allahu Akbar!"
"Fuck you, I'm Millwall!"

"Hey, you're robbing this girl!"
"Keep out of this and we won't stab you with these knives we're carrying."
"Fuck you, I'm Millwall!"

"What you're wearing is disrepecting the local culture"
"Fuck you, I'm Millwall"
