Top definition
A man sometimes large over 280Lbs who likes to sit and spend their time creeping around malls, stores, and every public place one can think of. Can usually be found anywhere in malls or stores and on sides of roads. Ominous men can be any man who looks like a creeper. Some activities of an ominous man include sitting alone eating in food courts looking creepy, walking around places with having no reason to be their, buying strange things at convenient stores, driving weird looking cars like vans pickup trucks and old volvos, and if they are seen on the street corner they can sometimes have dogs that look just as ominous as they do.
