Toilet paper. Proper everyday British phrase you’ll hear in any house, pub bog, or dodgy work loo. It also got legendary in 2020 when everyone started panic buying like the nation was about to wipe its way into the apocalypse. Sounds harmless, but say it in a Tesco and you’ll still feel the tension.
"We’re down to one loo roll and the flatmate’s done a curry and three coffees. I’m sprinting to the corner shop, pray for me, yeah?"
