I invited some otfers once
dangerous dave and someone else. I remember her housemate over hearing me joking that I invited a "dangerous dave" and she got really scared that some random off the internet was going to trash her house and kill us all. so to make it look like I was joking, I said "yeah and rapist robbie is turning up too" - anyway she thought it was a joke.
imagine her surprise when, a few hours later, my mate rob turned up and I shouted "hey rob!". she told him to get out because she thought he was a rapist. his face was a picture.
that took some explaining.
