The term "plodrock" was originally coined by musician W. EvanWalker in 2010. It refers to amateur music, generally pop/rock, that is dull and unmoving, songs that attempt to move the listener, but, in fact just 'plod' along, not really moving anyone and is usually really dull and boring.
Plodrock usually never hits the airwaves, it usually floats around on demo tapes and friends of bands who are trying to be discovered but never are.
Eating as much food as you possibly can (even if you're not hungry) when it is provided for free (such as a party or given as a donation) because you are too poor to buy your own food and don't know when you will ever eat again.
I wasn't hungry when I went to my little cousin's birthday party, but eating out of poordom was a must since I blew my paycheck at the bar.
