When your mother does something that merits no other response than getting a W tattooed on each of your buttcheeks, and doing a cartwheel in front of her resulting in "wow mom wow"
When tom's mother couldnt find out how to use the VCR again, Tom's onl response was Wow Mom Wow
An introspective moment when you realize how freakinggreat your life really is.
*While looking at the ocean and holding the hand of the one you love*
You: "I'm having an Oh Wow Moment."
Lover: "Awh! I know! I can't believe this is real life. It's all happening like a fairy tale."
