When a perfectly intelligent woman has sex with a totally inappropriate guy or a total jerk. His sperm has totally screwed up her mind so she cannot think straight. The only thing that can cure sperm poisioning is to stop having sex with the dude.
Alice: What the fuck does Cinderella see in that asshole.
Tinkerbell: IDK, After talking with her yesterday, I think she has sperm poisioning.
Alice: Shit, we lost her until she dumps his sorry ass.
