What makes a place call certain things those things? Midwesterners call soda, pop, while people where I grow up call every kind of soft drink a Coke, even if it's not really a Coke.
I've noticed that guys in Texas call their guy friends their "buddies." I never heard guys call other guys their buddies where I grew up or where I lived before I moved to Texas. But in Texas I hear it all the time: "I'm meeting up with a buddy of mine" or "He's a buddy I went to college with." I wonder why that is. I used to think "buddy" was a word little kids used. Apparently I was wrong.
