gahy
A gahi is someone who loves being silly and makes you laugh even when you're tired and just want to sleep.
My brother is a gahi. He wore pajamas to lunch and said, 'I'm a gahi, and I rule this day.'
My friend DM'd me: 'I'm a gahi, and I'm going to eat pizza for breakfast.'
At the park, the gahi ran around like a madman and said, 'I'm the gahi, and I'm the best.'
