Flavored coffees, however--gaaaahhhhh.
Oh man, I try some awful Starbucks* thing every Christmas, never learning the lesson that any alien flavour in coffee instantly renders it revolting to me. I can't take coffee-flavoured stuff, either. Ice cream? Cake? Not me, man. I love coffee though.
*Just in case: yes, I know the lesson should be "don't go into Starbucks"
