I agree with all of those!
And I'll add:
Pickles
The hipster movement (I could write a whole paragraph about why I find that annoying but I'll refrain)
Chick flicks
Twilight (gag)
Instagram
Country music, and a lot of people seem thrown off by that since I grew up in a tiny town surrounded by classmates who loved country stuff
Kool-aid
Jullianna, I'm with you on the Ugg boots. Ugh. Pun intended.
