You ever been petting a dog and you find that spot on their belly that makes their leg do the Thumper thing?
You've got a spot like that too and it's on the top of your head. Problem is, you can't really access it as well without a tool. This is that tool to give you that human equivalent experience.
Also works well under the influence, if you catch my drift ;) Great way to make friends. People will trip out if they've never seen one.
