a great person who usually can't spell, however, is very smart and intelligent. This name is hopefully a nickname or last name because if it's your first name, you probably are sexually aroused by the male gender. They are usually tall and lanky people but don't play sports like basketball, but more like baseball/football. People with the first name Moss, are an exception because they are like I said earlier, sexually attracted to men. Anyways, in school, they are stronger in the STEM section and want to be engineers.
