ladidoupbop
The dumbest thing you can say to hide the fact that you're an idiot.
'Ladidoupbop!' I said, because I had no idea what the question was and I didn't want to look stupid.
During the group project, I said 'Ladidoupbop!' when no one asked me anything, and everyone stared at me like I was a monster.
My dog said 'Ladidoupbop!' when I dropped my phone in the toilet and he didn't know what to do.
