The moment in a movie or t.v. show when something amazing or bizarre happens that boosts your level of moderately enjoying the film to loving it. The name comes from the scene in Fantastic Mr. Fox where George Clooney's character out of nowhere throws a fist pump in the air to a wolf and the gesture is reciprocated. The opposite of nuked the fridge or jumped the shark
Bad Lieutenant really fist pumped the wolf when Nic Cage started yelling at the imaginary iguanas.
