Gabbadabler
A weird toy from Egypt, once used in rituals, now it's just for brainless kids. Gabbadabler is a word used to tease someone who acts like a total idiot.
My dad says, 'You're a gabbadabler!' after I tried to ride a broom like a horse.
My teacher writes: 'You're a gabbadabler, go to the principal's office.'
My friend texts me: 'You're a gabbadabler, I swear on my life.'
