Answer

English rules come a distant second with advertising.
Here 'snuggling' a glass of scotch' means they were snuggling (curled up together) around a glass of scotch.

It's not correct English as it was written, but there are no real rules in advertising - only the message/image is important. And here we are allowed to  imagine the two cosily curled up together each drinking some scotch.
