When one or a group has the need to celebrate an event or accomplishment but has recently celebrated in the form of alcohol consumption and finds it necessary to have a relaxed celebration, ie "chill".
Yeah man, last weekend was a little crazy, but like since I got in William and Mary we needa chillibrate this weekend.
v. (chill-uh-brate): 1) to celebrate a significant event in a very relaxed manner; 2) to celebrate an insignificant event in an appropriately insignificant manner.
Instead of going out this New Years Eve to a loud club, I think some friends and I will just stay in and chillabrate.
When my co-worker comes back off her maternity leave, I'm going to buy her a burrito for lunch and chillabrate her return to work.
chilling or relaxing but in an exciting and social setting or manner. (Versus just regular "chilling" when you are busy or tired... a Chillabration or Chillation is chilling with friends and having a good time. You just happened to be radiating happiness about you while you do it!)
*Chillabration and Chillation are the same thing*
"My 21st Birthday happened to be a "sexy" chillabration!!!"
"I'm chillating right now and it is awesome!"
