The haybaler is the classic sex move where
one does the following:
1. Shave off all
one's pubic hairs and put them in a little bag.
2. Start having sex with someone doggy-style.
3. Take the shaven pubic hairs out of the bag and stuff them in the ass of the fucked doggy-style person.
4. Stuff the cock in the person's ass and
ram the pubes down.
5. When the person shits next, they shit out a pubic hair/shit hay bale.
