speed demon 

A person who tries extremely hard during practice. This teammate will exert all of their energy by sprinting, to "one up" someone else to lead the group. This will happen at appropiate and inappropitate times. When somebody takes part in this act, the other teammates tend to get aggravated. When a person is a speed demon during practices. Doesn't necessarily mean he or she is the best or fastest in the team; just means they practices intensely. This word is used in a neggative way.

speed demon 

A person who loves any of the major stimulant drugs, such as amphetamine, meth, cocaine, etc.

Speed demons all pretty much end up in the same place; dead, jail, or or on the streets. For some it can take just months, for others it can take years.

Jacks such a speed demon, hes always lookin for some meth to shoot. Hell prolly be dead or as good as dead in a year.

John loves the rush from amphetamines. He does speed bombs once every couple of weeks. Seems manageable enough now, but its slowly taking control of him.
