Twitter Dom
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.
Your Twitter Dom pushes his peas under his mashed potatoes and yells "Done!"
