look up any word, like wcw:
 
1.
A 50mm prime camera lens with an f-number of 1.8 or lower. The first lens to earn this nickname was the Canon EF 50mm f/1.8 II, introduced in 1991. Nifty fifties are cheap to buy, have sharp optics, and give amazing bokeh.
Yeah, I got a huge collection of zooms and wide angle lenses, but when all else fails, the nifty fifty always delivers.
