When I make popcorn, I like to melt some butter, then add hot sauce and honey. I don't know why everyone I know thinks it's gross, but I think it tastes great. Plus, it covers all the bases of flavor: Salty, spicy, and sweet - the perfect snack!
Also, I like mayonnaise on my french fries. It's something I picked up while living in Europe, and it's not really weird, but fellow Americans tend to look at me funny. I also put mayo on my burgers.
Finally, my dad makes some crazy awesome praline bacon.
