There was another post about the name Delta Variant. It started with a joke that when you sleep your brain emits delta waves, so you’d have to be asleep to believe the Delta Variant hoax. Some people added interesting ideas: the symbol for Delta is a pyramid, and they’re planning on calling the next hoax variant “Lambda”, whose symbol is a pyramid with its bottom dropped out. Delta symbol is used in math to signify change. aka Reset.

There are beta and and gamma variants that appeared before delta, but they spread less widely so got less attention. But they weren’t skipped over: https://timesofindia.indiatimes.com/india/covishield-covaxin-work-against-sars-cov-2s-alpha-beta-gamma-delta-variants-government/articleshow/83849663.cms
