(Verb) A 'portmanteau' consisting of the words Jacket and Huffing.

The act of sniffing an individual's scent off an article of clothing that said individual discarded or left behind accidentally. Typically committed towards a person who is known to have a distinct or pleasant smell. Used in a negative connotation, as it is often done in secret - albeit harmless. The enthusiasm and force of the inhalation usually increases with the creepiness of the one practicing the behavior.

Not to be confused with the homosexual act.
