21. I hate it when people say "Cali" instead of California.
I will never use that word. Unfortunately everyone and their mom refers to California as "Cali" here in MN. The worst part is they always say it with a MN accent, but trying to sound "cool." They over emphasize the a, dragging it out even longer than they normally draw out vowels. I used to think that the only people who called California "Cali" were people who were not from California. However, I've come to the sad realization that this is not true and have heard California natives refer to it as such. People, PLEASE STOP.
