Sneakyware 

Software that gets installed while installing another program, such as toolbars for your browser, or other software unrelated to the program you intended to install. Sometimes during the installation process of the intended software you are allowed to opt out of the sneakyware installation, sometimes you are not.

Joe: Man, why do you have so many toolbars on your browser.
Bill: They were sneakyware installations.

Sneakarette 

Last cigarette of the pack that is sometimes obscured by the foil lining. Especially problematic in 'soft pack' type of cigarette packs.

Whoa! I almost threw out this pack, but found a sneakarette in there.

Sneakarette 

A cigarette smoked in secret. When you have to sneak a cigarette so people don't find out you smoke.

Work was really stressful today so I had a quick sneakarette before my mom came home.
