A little bunny from a song who had a habbit of hopping through the forest, scooping up the field mice and bopping them on the head. Bunny Foo Foo was later turned into a goon by the GoodFairy.
"Little Bunny Foo Foo,
I don't want to see you
Scooping up the field mice
And boppin' 'em on the head.
I gave you three chances
And you didn't behave
Now you're a goon! POOF!!"
When a male removes his cock from his pants and walks up to an unsuspecting female and thumps her on the head. If you aren't packing enough meat the thump will not be as effective.
My wife was sitting on the sofa the other day and I walked up and gave her the bunny foo foo before she could look up from her computer.
