Back when Flash Boys came out, we all started calling each other Flash Boys. There was then a serious proposal to rename one of the strategies (the hedger, for added irony) Grandma Annihilator 3000.
When the KCG thing came out, one of the new grads was renamed “Power Peg” for a few weeks.
I miss the 2010s. It was a lot more fun when people leaned into stuff instead of being scared all the time.
