What is a “porno” haiku?
Well, isn’t that obvious? In terms of this web site, a porno haiku is supposed to be a FUNNY haiku that is about something sexual. Actually, the sexual part is pretty much optional. The guy who wrote this website was envisioning a mix of haikus where most of them would be something funny related to sex, but others would meet the “porno” criteria by virtue of adult language, not necessarily adult situations. As long as you remember that it’s supposed to be funny, the rest usually falls into place.
