Turd Wafter
Someone, usually a male who farts in front of his friends and then proceeds to use his hand to get right under the fart and waft it in a scoop like action out into their faces.
Rose would fart in a slighty sly manner trying to hide it from his friends, but only when things get too much he can't hold it in and proceeds to WAFT.in answer to this one would shout "oi Rose you fucking turd wafter!"
