My favorites follow:

1.  Misuse of the word *seen*:  As in "I seen the plane crash."

2.  Colloquial misuse of the word *all*:  As in "I'm like all surprised that
    you are like -- all worried about how I -- like speak!" (accent on
    last word)

3.  Non-reverent use of the word *God* in everyday speech in reference to
    mundane, non-spiritual matters: As in "Oh God. I forgot to put the milk in
    the macaroni and cheese."
