Gabwah
To be so taken aback by good news you start acting like a confused idiot. Also used when you think you’re in a movie and you start shouting lines.
My mom told me I could skip chores and I gabwahed like I’d just won the lottery and a pet dragon.
When my friend said he was coming to visit, I gabwahed and accidentally yelled 'I’m not a baby!' at the ceiling.
I found out I got into my dream school and I gabwahed so hard I knocked over my cereal.
