O-Bomba
A loud, stupid cheer you yell when you're too dumb to realize how bad something is. It's like a middle schooler's version of a standing ovation.
I just watched a cat fight a duck and I yelled O-Bomba because it was the most idiotic thing I've ever seen.
My crush texted me and I immediately said O-Bomba because I'm an idiot.
The pizza was cold and soggy, but I still said O-Bomba because I'm a moron.
