fumer

plural fumers

1. One who makes or uses perfumes.
2. That which fumes, something that produces or emits smoke or other vapor.

   The best fumer concepts evaluated to date employ pyrotechnic type mixes with additives (burning rate modifiers, gaseous output modifiers) and/or gas flow-restricting baseplates.
