A near-impossible problem put on engineering or science exams to determine who is using online resources like Chegg. Works best for take home-exams, since a student would be able to Google the problem more easily in a non-proctored environment. A professor will typically enlist a teaching assistant to post a convincing yet erroneous answer on sites like Chegg ahead of time. Also known as a "cheat check".
Joe: "How'd you do question 5 on the thermodynamics exam?"
John: "I found the answer on Chegg. It looked right."
Joe: "You fell for the Chegg bait. The TA posted that answer, and there's an intentional error in it!"
1.) When someone asks what Chegg is, this is the appropriate way to respond.
2.) If someone talks to you only because you have a Chegg subscription. When they ask you for an answer to something, respond in this manner.
1.) Dan - "Hey Jim, do you have Chegg?"
Jim - "What is Chegg"
Dan - "Chegg ma nuts"
2.) Sam - "Hey do you have the answers to 5.6 homework on Chegg?"
