A person who injures themselves or others on purpose, fakes illnesses/injuries or makes up outrageous sob stories to get attention/sympathy from others. Derived by Munchausens Syndrome, which is named for Baron Munchausen.
A psychological afflication, frequentlytargeting older women, in which the afflicted subconsciously sabotage high price items in order to create an excuse to go shopping.
Munchausen iProxy is a condition where a device owner creates the appearance of problems in a device, typically their own phone. This may include injuring the device (dropping it into a body of water, cracking its screen, etc.) or otherwise altering its operation. They then present the device as being non-functional in the hope of obtaining a newer and better device.
I heard that Karen "dropped her phone in the toilet" the other day, but she was raving about the latest iPhone last week; this seems like a clear case of Munchausen iProxy.
