Even before reading this thread, I was going to say "Cosmo magazine dating tips". Also it's breakup revenge tips.
I don't often consider people outside of certain political magazines to be literally psychopaths, but I'm willing to make an exception for Cosmopolitan.
Cosmopolitan is so absolutely batshit insane that it could be used as a guide for how not to behave.
God i read this and immediately thought of what i would tell my hypothetical future daughter who reads Cosmo.
Me: Look, sweetie i saw this under your bed and i think there's some things we need to talk about.
Future Daughter:What? it's just a fashion magazine.
Me: Yes, but i'm worried about what would happen if you followed any of these sex tips.
FD: Dad, i know about using protection.
Me: no, i mean that if you ever.....*looks at article* "shake your man's testicles like a pair of gambing dice" HE WILL LEAVE YOU.
FD: But the magazine says it drives guys wild!
Me: If by wild you mean filled with a deep passionate rage, then yea, it'll totally do that.
FD: You mean they don't like it?
Me: I mean they hate it. If there is one thing men of all colors and creeds hate and fear, it's having their privates abused.
FD: Then why would they put that in there?
Me: To ruin your life, sweetie. The fashion magazines are doing their level best to try and ruin every chance of happiness you'll have from now until menopause and the sooner you learn that their advice is the spite filled venom of sociopaths who resent your ability to love, the happier you'll be.
FD: Thanks dad!
Me: you're welcome, hun. Now here's twenty bucks. Go see a movie. Your mother and I are going to try all of these tips in reverse and see if it gets us anywhere.
