I'll be honest I initially started because I work a customer service job and everyone used to be worried about even saying little things that were deemed offensive, yet true and often funny. I began making fun of myself via my sexuality and my indeginious ancestors, then between diverse and non-pc family and friends I had a pass for everything but the "n" word, so I started making fun of everyone while requesting my coworkers to make fun of me.
It certainly boosted morale at my store since I moved there two years ago, and everyone's a lot more loosened up, level-headed and easy to get along with. We're like a family now. At the same time it's like how it was pre-2016 when everyone just enjoyed life and laughed a lot, getting through life without walking through minefields.
