look up any word, like blumpkin:
YayGod is an exclamation like WOW! YESSSSS! you may use it even if you have no religious backround at all. It basically means YAY!
If you just got a good grade on a test that you didn't study for- you shout YAYGOD! OR If you get out from school early because of snow- Shout YAYGOD!!
