Oh My Cron!
The exclamation of aghast fear when hearing of the new Covid-19 mutation. Combines Oh My God, Omicron, and Cronus the destructive, all-devouring Titan King of Greek Mythology.
Omcfy stands for oh my cool fucking yeah. People use this combo when something very surpricing happens. This is a way of showing excitement for some good news or just casually being flattered by something.
OMCL is short for "Oh my cabbage lord".
It's basically just like OMG except people who say OMCL are people who are in the cabbage religion and they say OMCL because they pray to the cabbage lord.
