Scag- cigarette.

The word, "scag", was coined in Northwest Ohio in 2007. It has since spread to most major metropolitan areas and college towns in Ohio. Predominately, the word "scag" has taken off in Toledo, Cincinnati, and Columbus. Bowling Green, Ohio and Athens, Ohio have reported moderate usage. Cleveland has yet to catch on as of late 2010. It's simplicity and rough, rugged, lackadaisical sound has been key to it's success. The word has also been known to be instantly understood even if the recipient of the word in conversation did not previously know of the term. This can, in part, be due to it's phonetic relation to "cig", short for cigarette. Nonetheless, the word "scag" has proven to be very appealing and fitful. It personifies the gritty, dirty deed of smoking a cigarette with great effectiveness. Common variations include scug, scaggy, scud, scud missle, scaggy pie, or scrag. The "mix and match" vowel options are numerous and quite a treat. Early projections predict the word should start to spread through the Midwest by 2014. It is hopeful "scag" can make it to the Rockies by 2020.

Example 3:

Steve-O: There must be 200 frickin' scag butts in the front yard. Get those outta there. And stop smoking, J. Come on bud.

Jordan: Call the cops.

Get the scag mug.
A Cadillac Escalade. Synonym: Bush-mobile. So named because it is ugly and useless, like a grotesquely obese woman, and an expensive, absurd waste that costs the user up to a thousand dollars a day, like heroin.
When I drive my Mom's Scag to the gas station every day, all the girls in 11th grade think I am a playa. I am sure that is why they laugh and point when they see me.
