If you don't get what she's tryna say, Dave Chappelle made this joke in his Netflix Special "Deep in the Heart of Texas." Joke is 22:20 if you need the time. If you don't got Netflix here's the transcript.
"And me and my white girlfriend are at home one night, and we’re just doing what lovers do. Maybe she’s butt-naked and she’s down on one knee, giving me a hand-job. I love a good hand-job. And she’s really jerking me off. You know, getting her obliques nice and tight. I got a huge dikk, so she’s like… [grunting] And I’m like, “Wow, this really feels wonderful. I think I’m gonna come.” And then she looks up at me and goes, “Come in my face… ******.” I know, that’s a tough one. Well, what do you think I’m gonna do? “Hey!” That’s no time for integrity, ladies and gentlemen. I’m busting that nut in her face. I’ll sort through the ethics later."
She's trying to disparage bucking using the idea "White women love black male bodies but don't respect/love black men."
The issue with it is this is a point that women commonly use with other women in regards to sex with men who don't respect them, but men as a collective simply don't care as much about this kinda thing. PAWG is a PAWG is a PAWG.
