The story of the Spread Called Dip

Today mom and I were making some shrimp dip. You did notice its called dip,right? Well, as mom was throwing stuff in a bowl mixing everything together I remembered we didn't have any big shrimp to dip in it. So, while I was thinking this and mom was mixing, I opened the can of "tiny shrimp". I asked mom "How are you supposed to dip these in there?"(while waving the tiny shrimp around to make my point) and, of course, with one quick crazy look at me she started laughing! Soon, I found out you don't dip shrimp in shrimp dip but, rather, you spread it on crackers or something.  Still, I think it ought to be called shrimp spread since you spread it you don't dip it. It just seems wrong to call a spread -dip- as if it isn't worthy of the -spread- title.
Anyway, maybe I'm just a little bit crazy and the spreadable dip would prefer to be called dip rather that spread? Ahh, who knows...
