Brain Rape

When something someone encounters causes so much thinking/confusion that the person feels violated.

Math problem: Betty leaves her purse in a store at the mall and averages 36 mi/h on her way home to Glenville, 140 miles away. Honest harry discovers her purse and starts after her one hour later. If he averages 48/h, how long will it take him to catch betty? Will he catch her before she reaches Glenville?

Jim: Dude, I think I just got brain raped.
