Pabda
Pabda is when you're so dumb you think being loud is a superpower. You’re like a kid who thinks he’s a wizard because he shouted at a tree.
'He's a pabda, he tried to conquer the internet with a megaphone.'
'That girl is a pabda, she thinks 1+1=3 is a breakthrough.'
'He's a pabda, he thinks Roblox is the only real world.'
