Breadferdux (shortened version of "bread for ducks") describes an event or thing that you naturally get super excited about. Such things you get excited about can happen in the future, as well. Breadferducks is a way to express a positive thing that makes you scurry faster toward it. In this sense, it can also describe interactions where there is high demand for limited supplies of something. It can also be used as a safe-for-work substitution for cluster**ck.
They said the competitive application process was a breadferduck, but they were all breadferducks when the acceptance letter arrived.
In the context of air hockey, specifically a well-worn game of air hockey that may be found in a local tavern, a "dirty bird" happens when your opposing team scores three goals in quick succession in a row. The use of the term "dirty bird" would be especially appropriate when the team happens to score three goals through a small-but-exploitable gap in the left side of the goalie net. The term "dirty bird" is said gruffly, never sweetly.
In fact, if you know someone who complains a lot under their breath, partly hoping to be heard and not be heard, then that is the voice you can use when you say "dirty bird."
You can also say something is a "dirty bird" whenever something less than desirable happens.
Example 1
Person 1: Hey, you just scored three goals very quickly in a row using similar techniques that exploit a gap in my goalie!
Person 2: I did. That's called skill.
Person 1: (Mutteringly) That's a dirty bird.
Example 2
Person 1: I ordered a sandwich, but they gave me soup instead.
Person 2: Oooh, that's a dirty bird.
