NASA - representing "Nice And Safe Attitude"
Used as a salutation, or farewell –an interjection
Popularised by a clothing brand worn by some in the late 1990's UK rave
scene.
At
first glance, the garment would appear to be an official National Aeronautics and Space Administration or NASA product, as the logo used the
worm font used by NASA. However beneath the main NASA text body, it would state "Nice And Safe Attitude".
