I was given this version of the poem -- instead of Boo-ing, it's called Ghosting, but it's the same thing 
This poem is meant to be in / attached to a bag of treats left on the doorstep, along with a ghost cut-out which is to be put on the door to show you need be Ghosted no more --- the peom explains it all
Late last night, we left you a treat.
The tradition is fun, one we hope you'll repeat.
Take the ghost and pin it on your door,
to let others know, you need ghosted no more.
Now it's your duty to pass on the surprise,
to two more families, we must advise.
Gather some treats and deliver them soon,
within two nights, under the light of the moon.
Include a ghost with each package you give,
along with this poem for the tradition to live.
