Top definition
A term used to express excitement and anger and about any emotion imaginable. But be careful, people might assume you are literally giving birth to cows. If you choose to play along with this childish idea, make disturbing groans while squeezing your buttcheeks together. And people may ask you where you keep your cows. Tell them that you keep them in a pin behind your house!

Suzzy: Oh my goodness, I'm gonna have a cow!
(Friends throw a surprise birthday party)
Friends: SURPRISE!

Herald: AH! I'm gonna have a cow!
(Also consider... Trips and falls on school stairs in front of hot seniors)
Tina: About 24 cows just escaped my pin... ;(
