Festivate

[Dianne]

To have a festival, celebrate, and/or party with great [zeal] and to an almost superfluous extent.
The word combines both festival and celebrate in order to describe a formerly unknown level of [revelry]. Instead of the normal levels of celebration, partying and festivities, this transcends popular convention to ascertain a deity-like level of merriment.
An occasion in which this occurs is known as a [festivation].
