When you have a lively party or a festive celebration of any kind, you jollify. Some people jollify just because it's the weekend, while for others it takes a special occasion to really let go and jollify. While the noun jollification is still occasionally used these days, it's rare to hear someone use the 1800's verb jollify. Both words stem from jolly, which has an Old French root, jolif, "festive, merry, or pretty."
