For those who ask...
What Does “304” Mean?
As a slang term, “304” is used as an alternative to the word “hoe.” Sometimes it’s used broadly to refer to promiscuous women in general. Other times it’s used to refer directly to prostitutes and other types of sex workers.
The origins of 304 come from digital calculators. If you type “304” into a calculator and then turn it upside down, it looks like it spells “hoe.” It’s the same idea as typing “8008135” into the calculator so it reads “boobies.” It’s a ‘90s kid thing, you wouldn’t get it.
To add to that, "304" rose in popularity in order to avoid bot censors that would automatically remove online posts that included the words "hoe", "whore", or the like. (and would often ban those who posted such terms)
At the risk of disillusioning you, digital calculators became quite common in the 1970s, so we did most of the things you mentioned as belonging solely to the 1990s. “7734,” for example, was obviously “hell.” Yep, you ripped us off.
And we ripped off the kids from the 1950s, and earlier, regarding other cultural stuff as they probably did someone else in turn.
So, welcome to the old geezer club of cultural appropriators. EVERYBODY is a member!
