I HAVE A BETTER ANSWER THAN ANYTHING HERE THAT WILL RESULT IN MORE SUFFERING AND MISERY THAN YOU COULD EVER DREAM POSSIBLE.
Ok. So here's the deal. Have you ever handled fiberglass insulation? Without gloves or a long sleeve shirt? What about working with it for an entire day and getting it all up in your business...your hair, clothes, your everything?
Nothing sucks more. I would rather be kicked in the balls twice.
Get just one good piece of fiberglass insulation. A little older is best. 'Fluff' it a little and spread it in some choice articles of clothing; rub the honeysuckle all over the insides of shirts and pants and anything else he wears. The idea here is to get little pieces of the fibers all over the clothes. They will work their way in to his skin and stay there for at least an entire day no matter what he does. A shower will provide only moderate salvation, much akin to your soul being only half-way in hell. Set aside some stuff for yourself...hide it under your matress or something.
He will don the clothing. It will be a few minutes before true misery sets in, but it WILL come, and he WILL rue the day that he touched your honeysuckle. He will fear you when you wield this power. There will be hours of unstoppable itching.
WHERE TO FIND INSULATION:
-Construction sites
-ATTICS HAVE TONS OF INSULATION JUST CRAWL UP AND GET SOME (find scuttlehatches in bedrooms, bathrooms, or more frequently in closets)
-Alternatively, try removing a small section of drywall out in the garage. Bound to be some there. Just put the drywall back.
Be advised, though; you will absolutely want some gloves to handle it.
Afterward, I recommend a double washing, to be sure you don't inflict this upon yourself inadvertently.
