a combination of steak, motor oil, the interior of a Ferrari, and popcorn

Very potent aromas each and every one, Alex Williams, but in combination? The scent of a Ferrari cannot be improved by motor oil, nor popcorn by steak.

Perhaps we need a dispenser which will release these heroic masculine odors in sequence, like the succulent courses of a feast, not in combination.

An olfactory feast! You have the germ of genius there, Alex Williams.
