When I sign..it doesnt matter if it is pop or soda cuz the sign for it is the same.
When I talk with hearing people, I probably would say "pop"
One time, I paged my friend who was running to the store asking her if she can grab me some pop. I typed wrong..I typed "Can u get me some poop?"
She replied saying "WTF?" and I was like "huh? what? I am sorry for asking u to get me something if it bothers u. Geez!" She paged back said "I am not getting poop for u my dear sweetie!" Then that was when I realized my typo..that was too funny!
