To act like a total brat and give adults the worst kind of grief. It’s when kids try to sound fancy just to make adults look like fools and then stop talking because they’re too dumb to keep going.
My kid obsternasigged me in front of the whole class. I had to pretend I didn’t hear him.
She obsternasigged her mom by using the word ‘quibbles’ and then cried when she didn’t get ice cream.
He obsternasigged the teacher by saying ‘I’m not a skitunge’ and then forgot what ‘skitunge’ meant.
