The act of forcing oneself to endure, without physical signs of discomfort, otherwise unbearably low temperatures by simply refusing to wear a jacket.
If one shows physical signs of discomfort whilst refusing to wear a jacket he or she will be subject to ridicule amongst his or her friends, e.g. being called a dickhead, therefore to avoid such ridicule the mind will force the body to cope with the cold.
For added incentive one can carry their jacket with them and still refuse to wear it. Carrying a jacket whilst being obviously cold makes the person attempting to exploit The Dickhead Factor appear even more foolish thus increasing the levels of ridicule they will have to endure and their incentive not to show discomfort.
Person A (wearing jacket):- Hey, aren't you cold out here? It's freezing!
Person B (not wearing jacket):- Nope, I'm fine.
Person A:- wow, you must be immune to cold or something.
Person C:- Don't fall for it, he's just exploiting The Dickhead Factor.
