Gally gal
Gally gal is when two girls greet each other like they’re about to start a dance-off or a food fight.
'Gally gal!' she said, then challenged him to a pizza eating contest.
'Gally gal!' he said, then grabbed a soda and started spraying her.
'Gally gal!' they said, then started a whole new feud about the best song ever.
