g-argh-bbledygook!
gobbledygook is like when your brain melts from too much stupid stuff. it’s jibber-jabber that sounds fancy but means nothing.
My teacher said, 'This is the most gobbledygook I’ve ever seen!' after I wrote 'flibbertigibbet' on the test.
He texted me, 'Why did you send me gobbledygook? I was trying to sleep!'
The guy at the airport yelled, 'What the hell is this gobbledygook?' while I was talking in code.
