Cap'n Crunch - I can't actually eat this as it was intended (cereal + milk). Even as a dry snack, it's just too nasty-sweet+mealy-mouth.
As a kid, I ate bowlfuls.
Coke (and lots of sodas, like Root Beer, Grape, Orange) - JESUS they are too sweet. I WATER DOWN MY SODA IF IT IS THE ONLY THING AVAILABLE. I really do. Same applies to sweet beverages in general. Diet Coke I can drink, but it is still very, very sweet.
I hate junky-crap icing (which is what is found on 99% of everything). I've become much more discerning when it comes to icing. Crappy icing ruins otherwise excellent cupcakes/cakes/cookies, etc.
Excellent icing, however, I fully enjoy, though I still need the cake:icing ratio to be appropriate. I hate when there is too much icing....just like I hate it when there is too much cream cheese in a bagel. THERE IS A PROPER CREAM CHEESE:BAGEL RATIO, but too many folks ignore it.
Damn them to hell!!!!
