Exploding heads.

Trigger is HeadBoom.

Nearly all the images were tagged with one of

• Headless

• Faceless (has something above the neck, but no real face)

• Lower_Face (everything from roughly the nose up is gone)

• Full_Face (just the top/back of the head blown off)

The explosion can be described with

• Smoke (might be able to add a colour)

• Fire

• Explosion

• Glitter (only a couple of samples, not sure if it works)

• Viscera - which almost guarantees Guro.

If you mention facial features (particularly with Viscera), you may find them contained in the spray of blood and mess. Specifically, there were images tagged with

• eyeball

• teeth

• tongue
