Lets see.
Got into a small fender bender at a light when I dropped (sp?) my "tin" on the floor and was looking for it.
Grabbed the wrong "cup" from the dashboard and took a big swig of tabacco spit.
In an old truck, used the floorbards for a spit toon (sp?)
"chewing" while whitewater kayaking, hit a pretty big hole, went upside down, hit my head on a rock, swallowed a BIG dip and started throwing up going down a nice size rapid.
Accidently dropped an open tin while in someone elses car.
On a plus note, when I used to drink, a tin was great for opening up a "non twist" bottle of beer.
Since married, pretty much given it up except from time to time when around some old friends (since I gave up drinking, sort of a "bond" with some old buddies for better or worse.
What other names for chewing? Used "chew", "dip" and "rub".
Did have a buddy who had a girlfriend who chewed. Hate to admit it, but she was pretty good looking and for some reason, watching her dip, really made her more sexy.
