I have a thing against Copenhagen, personally.
Years ago, while bartending when the patch was slack, i got hardcore sucker-kissed by a gal who had a mouthful of it and she slipped me the tongue. Left me spitting out little bits of snoose for the rest of the night.
Aaack! Worst kiss ever, even if she'd been an 11 on the 1-10 scale (she wasn't close, not to be cruel, just the facts).
Just the smell brings up bad memories.
I actually had two girlfriends that chewed. My biggest complaint, in both cases, was getting in my freezer and 'sharing' from my rolls. I keep a fair supply laying around... Always have. I do not like being jittery driving into town for a can at 2 in the morning. In both cases, eventually, that's exactly what happened.
The thing is, only the one of em chewed Cope. The other did Skoal with cherry liquor added in.
Kinda like women 'sharing' off my plate - I think they do that as an exercise to prove trust.
There are better ways to do that, I would tell em, picking bit's of their hand from between my teeth...
