Lacka Bru
Lacka bru is when you're telling someone something is so good, it’s almost criminal. You're not just saying it's good, you're saying it’s a crime not to love it.
That concert was lacka bru, I'm gonna scream it in my sleep and wake up my neighbors.
This music is lacka bru, I'm gonna play it until my dog dances.
That food was lacka bru, I'm gonna eat it and then I'll eat my homework.
