It's the opposite of a roast. While people in a roasting event would gather up to make fun of a single person, a buttering event has people gather up to adore, praise, and talk good about that person. Sometimes, it's extended to include everyone, so that each person has a chance to receive a variety of compliments. You can't talk bad about someone at a buttering event. The worst you can get to talking bad about someone is constructive criticism, guidence, and maybe a compliment sandwhich.
Coworker 1: Hey. Have you heard that the Coolerman and The Boss were feeling sad lately

Coworker 2: Yeah. They were feeling underappreciated, lonely, and unconfident.

Coworker 3: I have an idea! Let's have a buttering.

Coworker 1 and Coworker 2: That's a great idea!

Coworker 1: That way, they would feel more appreciated.

Coworker 2: A buttering event sounds perfect!
