Apparently the mere suggestion of a word can change the connotation of smells from "unpleasant" to "pleasant". This suggests that smells are basically agnostic and that we're trained to recognize whether they're "good" or "bad".
No word on whether subliminal suggestions can make a pussy smell good. All you girls could try an experiment, though. Next time he's down there say stuff like "buy a Mustang GT" or "you can have the whole garage for a workshop and I'll park the car in the driveway". If it leads to more pussy eating, you might just find that you don't mind walking through the snow to get to the car.
