Full Head of Steam 

In basketball, when a player has high speed and momentum. Usually used to describe large players driving to the goal for a dunk.

Originates from confused basketball announcers mixing up their words when trying to describe a player as moving “full steam ahead” before entering common usage.

Sometimes described as simply a “head of steam”.

Giannis is tearing down the court with a full head of steam!

Not many people are going to be willing to take a charge when LeBron gets a head of steam toward the goal.
