content: How to screw with a offensive feminist. Get your self on of those mini sprayers.  You know the kind that have breath spray in them. (Small size is more important than how much they spray.  In fact the finer the mist the better.).  Paint the exterior flat black to keep out sun light.  Fill that sucker with silver nitrate solution.  When some feminist asshole starts hassling you, wait until she selects another target and then spray.  Silver Nitrate solution is non toxic, tasteless, colorless, and odorless.  What it does do is turn black under sun light.  Even a barely damp handbag, coat, pair of pants, or skin will turn a deep black that cannot be washed out or even bleached out.  Takes about 3 months to ware off skin.  Works grate  and marks a feminist asshole for every one to see.
