Pinception
Where you find yourself lost in Pinterest after chasing the rabbit down the 'more like this' path and lose sense of which layer of pins you're in.
Crap, I can't remember how deep I went. Was it a pin within a pin? Or a pin within a pin within a pin? Pinception!
Pinception
The process of slowly tricking your male friends into liking Pinterest.
I used to hate Pinterest, but now I cant get enough of it. PINCEPTION.
