Smoothie, foodie, and especially hoodie.
These diminutive -ie suffixes are what your great grandparents attached to everything. Smoothie: no idea from whence it came. Foodie: the new Epicureans. Disgusting. Hoodie: Used to be awesome when worn by medieval mysterious types and 1980s athletes. Hood rats and slackers champion their wear today, but there's nothing diminutive about cultural rot.
