I’m still wrapping my mind around how this even works. ATM I use Debian for my laptop, so now my husband (already knowing I’d support an open marriage if he wanted one) should be a free target for sexual harassment? Is that the joke?
Not really, it just assumes that the Linux user has a girlfriend who's promiscuous. It's just a joke. That said, I am a male Linux user and my wife and I are poly, so it's extra funny to me.
