It's not a new idea:
Drake Accused of Putting Hot Sauce in Condom After Sex
After attending a party together, the woman alleged they went to his hotel and smoked weed before having sex with condom, which Drake ended up disposing of in the bathroom.
But the woman apparently had ulterior motives, specifically to impregnate herself. As such, she claimed to have fished the used condom out of the trash and put the contents into her vagina — except she said it felt like "pouring hot lava into her pussy."
She then went on to allege that after hearing her screams, Drake came to the bathroom and told her he'd poured a packet of hot sauce into the condom in a bizarre attempt to kill the sperm. And now, the woman is trying to sue.
I know of two dancers whom tried to trap men by intentionally getting pregnant - one already in a married relationship. In both cases the men bolted and wanted nothing to do with them (how do they figure a guy isn't going to hate being trapped like that is beyond me.) I can see men getting a little possessive of their sperm.
