ladidoupbop
A loud, ridiculous word you shout to pretend you're important.
'Ladidoupbop!' I shouted at the top of my lungs, because I thought I was being cool and everyone else was dumb.
During the talent show, I said 'Ladidoupbop!' and nobody knew what I was doing, but I still got a standing ovation.
When my teacher asked me a question I didn't know the answer to, I yelled 'Ladidoupbop!' and walked out.
