(internet history questions) ....where/who did the 50/50 dating & marriage conversation come from?

[videogamestashbox.com]

Certain terms and conversations I know where and/or who they come from...

• "Educated lame" = sergeant willie Pete (2006-2008) YouTube
• "Bed wench" = Tariq Nasheed (2012+/-) YouTube
• "Hair hat" = Tommy Sotomayor (pre 2014) YouTube
• "High value man" = Kevin Samuels (2021 +/-) YouTube
• Bla bla bla etc etc.

But where in hell did all this 50/50 expenses talk come from? ....Hell I probably should add this whole stay at home 1950-ish wife talk as well because non of that was apart of the black "gender war" discussion as far back as around 2015+/-




I will say that most of the stuff I saw was from catching conversations here and there on YouTube via the algorithm.
If anything spawned out of conversation on Facebook, twitter, Clubhouse(I think a lot of ish came out of clubhouse) I wouldn't know about it as I catch this stuff on occasion because it pops up on YouTube. I don't be searching the web looking for it. But that means the conversation will turn to new talking points out of the blue such as all this 50/50 talk.

Hence this thread question
