Baaaaaaaaase Threeee!!
Baaaaaase Threeee is the sound of a loser who thinks they're cool. It's the last thing you hear before you start laughing so hard you cry.
My friend said 'Baaaaaase Threeee!' after I beat him at Fortnite.
My neighbor shouted 'Baaaaaase Threeee!' when he realized he forgot his keys.
My little brother yelled 'Baaaaaase Threeee!' when I took his toy.
