A Murphy
A Murphy is the guy who’s like the best friend you never had. He’ll lend you his last dollar, help you cheat on a test, and still call you a friend when you fail everything.
My Murphy lent me his last dollar so I could buy pizza and then failed math.
He helped me cheat on my test and still called me a friend when I got caught.
He gave me his shirt when I had no clothes and still made me do my homework.
