Despite the criticism, I'm with Deez Nuts. Can't stand onions (unless in small enough quantity as to not bother the flavor of the rest of the food, and not large and slimy kind of onions. Especially hate them raw) or guac.
But to contribute 2 things of my own, I hate the inbetween period of the year when it's not quit warm enough to keep the ac on, but often warm enough to turn it on.
Also hate when things you depend on break. Could be a car, a chair, computer, favorite crystal penguine statue, whatever (not sure why you would depend on a crystal penguine statue, though. Silly willy).
