Motivational Kiss

The Hero is just about to face danger and possibly threatening task, facing down the Big Bad, barging into a burning building or even trying to clear a massive Bottomless Pit.

All his friends are depending on him, and time is running out, but he still may be a little nervous and apprehensive. He needs some sort of Heroism Incentive.

All he needs is a little peck and he'll be ready to go. A Motivational Kiss happens when someone, almost Always Female, gives the main protagonist a kiss that gives him an extra boost in confidence.

The kisser will often, but not always, be the protagonist's Love Interest or at least someone who he's been Ship Teased with in the past.

Examples

 * At the climax of Monster House, our protagonist, DJ, is faced with the task of climbing up a crane and dropping a stick of dynamite down Constance's chimney, destroying her once and for all. When he says that he doesn't think he can do it, his Love Interest Jenny loudly proclaims, "Yes, you can!" before kissing him on the mouth.
 * In Captain America: The First Avenger, Steve Rogers receives a kiss from Peggy Carter just before he boards the Red Skull's plane.
 * In Star Wars Episode IV: A New Hope, Princess Leia gives Luke a peck on the cheek "for luck" before he tries to swing over a precarious gap.
