look up any word, like slope:
 
1.
to be tossed about in a herkish manner whilst owning the passenger seat in your friend's car.
stop driving like that. you're herky jerkin' me all around.

damn my neck is still sore from being herky jerked. maybe if you didn't drive so fast up the mountain i'd be fine.

honey slow down. the kids are all getting herky jerked in the back.
