Someone told me it was someone who farts so hard that they knock things over. I don't think any of us really know what it means.
(both kevin and John don't know what a fart knocker is)
Kevin: You're a fart knocker
John: What's a fart knocker?
Kevin: You don't know what a fart knocker is?!
John:...oh...yeah, of course I know what a fart knocker is.
Kevin: You're a fart knocker
John: What's a fart knocker?
Kevin: You don't know what a fart knocker is?!
John:...oh...yeah, of course I know what a fart knocker is.
