the true deffinition is believing that one shape is superior to all other. Hatred without reason of another shape. ETC.
SADLY today that has changed.
In todays world this is what makes you shapist:
Mentioning shape in any way
Not being totally politically correct
Supporting your shape
Being 3d
Telling a shapist joke
Judging by dimensions
Disliking something someone likes
etc.
Real example of shapist
shapist: (insert shape here) is better than every other shape. I think that (insert different shape) people are disgusting and horrible and should die.
Idiot's example of shapist:
person: I don't like curves
idiot: OMG SHAPIST!
guy: I hate illuminate.
idiot: OMG SHAPIST
dude: My friend has balls
idiot: OMG SHAPIST!
man: I'm Multi-Shaped
idiot: OMG SHAPIST
woman: I'm proud of my shape
idiot: OMG SHAPIST
stranger: So an (insert shape) guy walks into a bar....
idiot: OMG SHAPIST!
