Basically charisma (the rizz part)
Think of it like “cha-rizz-ma.” It’s just a slang abbreviation, using only the middle sound of “charisma.”
Fellow old guy here, in my early 40s. I had to figure out where “rizz” came from before it really clicked for me.
Note: the reason it looks especially phallic is because Norway is missing. Because Norway isn’t part of the European Union, and thus does not use Euros as their primary currency.
