(n.) knockoff - a copy of
an original brand, often
priced dramatically lower than an
authentic. Commonly, the designs will have been altered a bit, or they will appear the exact same, but some small detail may prove they are not authentic.
"Woah, a
Dior wallet for $40.00? That can't be possible."
"It isn't. See? The interior isn't leather, it's plastic. And the
stitching is loose and
falling apart. It's definitely a knockoff."
