A play on "Murphy's Law," just with genitals. When you shave your downstairs area because you think "tonight's finally the big night," it almost 100% guarantees you will not get laid.

"Ah man, Murphy's Balls in effect."

When playing a co-op game, a Backstab Murphy is when one player desperately needs a powerup of some sort (usually health), only to be denied the powerup by his fellow gamer who they happen to be co-oping with.
Player 1: Oh, man. A health pack! Finally!
Player 2: SWIPE!!
Player 1: ... Did you seriously decide to go Backstab Murphy on me?
