(interj.) said when expressing happiness!

When yay just wont cut it

showing expressions of great happyness followed by a long list of exclamation marks. usually yelled by some freak who is over excited about something...i.e. what i do, a lot!!!!

Its an expression of joy

A word that my best friend Katie says. :) Yayness for katie!

Used in the same way as yay but it is better

The state of having a lot of yayness, or generally being in a very good mood. It can often result in other people becoming annoyed at the high spirits.
