British Tosser Trash Sign

This sign from York, UK, does something most public messages don’t: it shames litterers with a wink. Instead of dull “Keep our city clean” lines, it lists reasons no one wants to be guilty of—lazy, uncaring, selfish—then delivers the punchline: Don’t be a tosser.

Why It Works

• Uses humor to grab attention
• Leans on social pressure and identity
• Frames bad behavior as embarrassing, not rebellious
• Speaks in the audience’s local slang
• Keeps the message short and readable

Real-World Examples

• The NYC “Don’t be a litterbug” campaign cut street litter by 19%.
• Texas’s “Don’t Mess With Texas” reduced highway litter 72% in its first six years.
• Remember Smokey Bear’s “Only You”? Same emotional trigger—personal responsibility.
