O Yea
What you yell when a hot girl walks by, or when you win the lottery, or when your mom gives you money and doesn't ask for anything back.
O Yea, that girl just walked by and I'm gonna date her next week
O Yea, I just got a hundred bucks from my mom, I'm rich
O Yea, I just won a free pizza and I'm gonna eat it in my mom's face
