A hair cut that forms a perfect "helmet" shape around the head itself. Many times this can be accomplished by a horrible haircut and lack of caring in the morning tossed with a side of being a boner. This non-trendy look is usually seen on people with the name "Mike".
"Man, Mike walked in this morning with some crazy helmet head! Die it pink and he'd look like a penis!!"
