DnB rolling drum beat, jump up (roller) HOW TO?

hi can anyone tell how to make a (roller) in terms of a drum beat. preferebly aimed towards the jump up side.
i seen a post before and it mentioned something like ghost notes, im new to producing and dont know much so anything you post will be appreciated.
any links or diagrams would be appreciated, im on fruity loops so no reason stuff because its useless, unless it's recommended

i think you're doing this on purpose to get on peoples tits.
