A trailer for a movie with heavy use of explosions. The term "explosion trailer" is always preceded by a number indicating the amount of explosions.

Explosion trailers are light on serious dialogue and the audience is sometimes left wondering what the movie is about, other than explosions. The number of fourteen-year old boys who will see the movie increases exponentially with the number of explosions in the trailer.

Usually, a movie with an explosion trailer is not considered Oscar-worthy, unless it is for special effects. For the life of me, I can't recall an explosion trailer featuring Meryl Streep.
After seeing the seven-explosion trailer for Timecop III, all the boys in Ms. Shull's 9th grade homeroom couldn't wait to see it.
