Jacob's Law

This is a fundamental law of manhood. Jacob's Law is that when referring to ones penis in a jokingly or flirtatious manner, you must portray it as smaller than it actually is. This means you never let a girl down once in the sack.

Originating from the Australian outback at Jacob's Creek hence the name

Matthew: I was chatting to this girl last night and ended up having sex
Ben: ah nice, did you use Jacob's Law?
Matthew: yeah for once a girl was fine with my average sized penis

A way of asking if a person would like company for a period of time
