Boot-sniffer

An over-zealous volunteer firefighter that is so consumed with firefighters that he obtains pleasure or sexual arousal from sniffing the smoky aroma of bunker-boots of other firefighters. Boot-sniffers are known to visit fire stations while traveling, to secretly fulfill their fetish. Boot sniffers are best identified by excessive firefighter stickers on their vehicle or by their over-use of fire-related t-shirts.

That boot-sniffer loves to wear fire department t-shirts and share firefighter Facebook posts so people will thank him for his service.
