In the navy I ran into "dip" and "a can of dip" almost universally. Regardless of what your private regional term was people asked others if they had a can of dip on them. And asked to bum a dip. Happened everywhere I was stationed. At home near the Alabama border it was usually called "cope." Just like everyone in that area drinks "coke."
"Hey man, got any cope on ya?"
"Yessum"
"Aight, what kind ya got?"
"Kodiak long cut.."
etc. Akin to asking if you want a coke to drink and telling you we have pepsi, 7-up etc.
