@(you need an account to see links) I am right there with you... when I get gas for my car, I have been known to take in a big whif of that sweet gasoline smell.
And I have a few more in no certain order... mostly are food related:
I love fried Gyoza in Japanese restaurants so if I have extra Gyoza sauce, I drink it right form the little bowl. It embarrasses my husband every single time.
I eat sour cream on sloppy joes and beef stew.
I like to smear creamy peanut butter on Cheese Doritos.
And the worst one to most people... I like to eat ranch dressing with sphaghetti with full on tomatoe sauce.
