This is what happens when physicists start drinking...

A surprising amount of science communication and collaborative agreements gets done in bars at conferences. Sometimes the side effect of this leaks out when scientists deviate from the dry terminology. So this week, Nature has an article with the phrase "exotic electroweak penguin contribution" - apparently, to a drunk physicist, a modification of a Feynman diagram looks like a penguin. A bit.

I should admit that I like the idea of quarks having a flavour. Makes things a little more poetic, somehow.
