It means they’re having bareback sex and the man orgasms while inside her.
It should not be tolerated at the workplace. I’m forced to listen to this rhetoric because my shift isn’t done yet, and I can’t leave without getting fired. I’m forced into a sexual discussion without consent, and it’s so graphically disgusting that I feel nauseous.
It’s a euphemism designed to avoid explicit detail. You should be thankful for the phrase.
Also, it’s one of the most natural things imaginable, maybe work on understanding your own sensitivity rather than bringing other people down for being human.
By OP’s logic, you shouldn’t be able to tell anyone you are pregnant or that you have children because that eludes to the fact that at one point you’ve had sex. Next HR is going to remove the bathrooms from the office, because it assumes that people are pissing somewhere.
You probably also shouldn’t mention that you have a mother or a father because that forces OP to picture your parents doing the deed to make you. Same goes for siblings and grandparents.
