NOS

A recreational drug, often inhaled repetitively with the help of balloons. Causes about 12 seconds of euphoria. Often accompanied by a "womp womp womp womp" sound, not unlike the experience of laughing gas.

Pass me a balloon so I can fill it with NOS.

NOS

NOS is the acronym for New Old Stock. It's an item that is old, but ios not used. Since it never sold, it's technically "new" even though it may be several years old.

1967 Plymouth Barracuda Antenna. Chrysler made them and distributed them to Retailers. Stock was left over after they stopped making the cars.

No-nos

An idiosyncratic term to describe the long list of people over my lifetime whom I rejected when they asked me out.

The no-nos are a weird club of faceless and otherwise unrelated folks who sometimes wander in and out of my unconscious, sometimes bleeding into my dreams such as when this group was even larger than the one attending 45’s inauguration..

2.) Commonly accepted replacement for the term "Nitrous Oxide." However, this is not correct, and anyone who says "NOS" instead of Nitrous Oxide should be shot.
