gabba goo
A random, weird thing someone says in a Jersey accent. It’s like when you’re telling a story and just throw in a weird phrase for no reason.
'You know what I mean, gabba goo,' he said. I had no idea what he meant.
She said, 'Forget about it, gabba goo,' and then left me hanging.
He said, 'Know what I’m sayin’, gabba goo,' and I just stared at him.
