Gabwah
To be so surprised by something good you lose your mind a little. Also used when you start talking to yourself like you’re in a commercial.
I got a free pizza and I gabwahed like I was about to become a pizza god.
When my crush said he liked me, I gabwahed and started doing the chicken dance in the hallway.
I saw my dog wearing a hat and I gabwahed like I’d just discovered the secret to life.
