A Twitter Dom is a man who uses a black and white photo of himself in a suit and tie, showing only from the chin down to chest. They derive from the 50 Shades of Grey trend and personify a "Dom" persona on their account. In reality, they are usually middle aged men wearing fanny packs on family vacations or teenage boys who are "Domming" their "Littles" between rounds of Xbox.
