Is calling your friends 'unemployed' as a joke considered a sin biblically?

So me and my friends have this thing where we jokingly call each other names like 'unemployed' — completely mutual, no one gets hurt, and honestly it's just how we show affection. The more we joke like that, the closer we actually are. But then I came across Matthew 5:22 where Jesus says calling your brother a fool puts you in danger of hellfire. And I started wondering... does that apply to joking around too? My gut feeling is that it's kind of like acting — both sides know it's not real, there's no actual contempt behind it, and it brings us together rather than tearing us apart. But I wanted to hear from others. Do you think context and intention change everything here? Or is the word itself already a problem regardless of how it's meant?
