Nash

n., adj. Slang for a cheap and extremely shitty skateboard. Typically these boards can be found in Walmarts or any other large scale retailers. Nash's are usually a skaters first board. Signs of a Nash board:
-Wrapped in plastic with the trucks & wheels attached over the plastic
-Terrible wood quality which cracks and splinters from light impact, delaminates easily
-Plastic trucks or terrible quality metal trucks which stress and bend easily
-Bearings that are so slow and have so much resistance to spinning that it becomes impossible to maintain speed

The term was popular through the early 90's to early 00's (may have originated earlier) but died down in popularity in the 2k10's. It was a meme then, and still is a meme now.
Avoid purchasing, instead invest in a proper setup.
