Up your nan

What my brother tell me when we’re being annoying to each other

Me: he’s not ugly he’s just ginger
My bro: up your nan
Me: wtf

your nans dead

when something annoying happens or someone annoys you, you say “your nans dead” or “that’s dead nan”

teacher: “you boys will be staying back at lunch”
boys: “your nans fucken dead” / “that’s so dead nan”

matt: *spills raspberry cruiser on dylan’s white shirt*
dylan: “your nans dead”
