Gabbadabler
A stupid, bouncy toy from Egypt that kids love, even though it’s totally pointless. Gabbadabler is a word people use to insult someone in a funny and ridiculous way.
My friend says, 'You're a gabbadabler!' because I tried to draw a perfect circle with my eyes closed.
My brother texts me: 'You're a gabbadabler, I swear on my life.'
My teacher yells, 'You're a gabbadabler!' after I tried to sing a song backwards.
