Knowledge Shopping 

When someone criticizes you for being an idiot or not knowledgable either because you don't read books or don't keep up with news and current events. The person then goes out to a store and buys an item that if seen by the other would increase his respect of him. There are two results of this. The criticized person would then take the bought item and then never look at it or use it or they could return/sell it after a couple of days.

Jared: Mike you're a fucking idiot you don't know anything!!

Jared sees Mike

Jared to himself: Jesus Christ Mike is soooo smart!!

Knowledge shopping 

Person who uses others knowledge as there own for commercial purposes, without paying person or persons for knowledge accrued

John offered an interview to a candidate through a recruitment agency So that he could find out how to design a square, because he'd never designed a square before, and didn't want to get sacked by his boss for a lack of skills and knowledge he couldn't be bothered to update. So John knowledge shopped the skills from an undergraduate pretending he had a job on offer when he didn't. This practice is called knowledge shopping.
