a person who is offensive towards the sheenmeister. (charlie sheen) they may hurl abusive comments about his one night stands and drug addiction.
i was sitting at my table snorting crack cocaine with the sheenmeister, (charlie sheen) when i saw two young boys about 15 being sheenist towards charlie sheen, so, i went over to them, hit them round the heads with a chair, shoved crack up their asses, and made them get a tatoo with his name on it.
