Using lines from motivational or inspirational posters to spurr on or motivate an individual, usually during a sporting event or physical activity.

Peter on season 10 of The Amazing Race often did this to his partner Sarah, who had one fake, bionic leg.
Peter often shouted successories at Sarah while she struggled to do a very physical task and he sat there being lazy and useless.
