Someone, usually male, but can be females or couples too, who have a profile on a hook-up or swingers website/app, but only 'come on' when they need their hormones topping up. Usually by wanking at the thought of meeting another person, but never actually doing so.
Joey never meets anyone from this app, he's just a Fuel Light - he only comes on to fill up his wank bank.
