4-0

Derogatory slang for mall security guards/vehicles. Derived from 5-0, a slang term for police officers/vehicles.

The 4-0 got on my ass after I boosted that Clay Aiken CD from Sam Goody.

4-0

Often used by fans of finished club FC Barcelona when something doesn’t go their way and they get mad. Their biggest trophy and achievement in season 2021/2022. Used by them to annoy other people but they didn’t found out yet that nobody cares anymore.

Person 1: Real Madrid are winning La Liga this season, maybe UCL and will get Mbappe for free.
Person 2: 4-0.
