McDiesel 

1. a person being notoriously good at something, but is the underdog of it; an urban myth of a rookie that shows up at the last second and slowly assasinates other competitors

2. a person who is a cerebral assasin

As in Skateboarding a McDiesel skater is Torey Pudwill

As in basketball a McDiesel player would be Mike Bibby

In Modern Warfare 2 a McDiesel would be a sniper in a distance that only gets headshots
