Onesy

A one piece snow suit. Worn back in the day when skiing was young. Now commonly worn by thy Gaper. Comes in Solid or Multiple bright colors. Do NOT wear in Colorado or you shall get mugged.

For Gaper day, I decided to wear a Onesy.

onesie

a single cigarette sold over the counter by a retail establishment, instead of a pack of 20. useful in New York if you don't have the $8 for a pack. also useful for the quitting smoker who just needs one nicotine hit to take the edge off. onesie's are illegal in some states - eg Illinois 2009
