Yubbish (Yuppie Rubbish) is best described as the discarded, but often useful and/or tasteful items from mid-upper and upper class homes.
Apparently the best times to find yubbish is just prior to local council 'hard rubbish' collection weeks, where nature-strips suddenly fill up with all manner of discarded items, from broken vases to audio/visual equipment.
"Man I was cruising through Toorak the other week when I scored this awesome yubbish CD Player!"
Yarbish is a language, or way of speaking. Common Yarbish words include, "yarb" "boy" "jeah" "fuck" "shit" or any other profanity (many urban dictionary terms: such as "narb"). An appropriate way to speak Yarbish would be to use the dialect of the "Unforgivable" guy or the "Terrets" guy from YouTube. Speaking Yarbish is a good way to bullshit with friends and not give a fuck. (The key is to use unnecssary swearing).
