(I have a fever from hell right not and Im a bit weird in the skull)
I am designing a loose penis for ladies to wear to avoid mansplainers, I call it "Anti-mansplaining detachable declarative dick". Within its silicone housing is a speaker, a single board computer, a button and a battery.
When someone tells you that even though you're an expert at a subject they know better than you, due to their penis, a lady press the button and the speaker screams out "I AM A MASSIVE SCHLONG! I AM RIGHT!"
That way the dude will back off, terrefied that he has offended a dude instead of told off a woman.
I think I will sell about 2-4 million units in the first year, then levelling out for the next two years. Any investors!?
