That dreadful point in the day where the sun is too low in the sky to be blocked by your sun visor, but too high for it to be dark.
I was trying to nap on the car ride home, but we were so deep in malsolchroning that the sun shined through my closed eyes no matter how I was sitting. I had to take my jacket off and put it over my head, like that's a remotely normal thing to do.
An adjective denoting the already waxy, slightly washed out sound of a brand new vinyl record you just barely opened to play. Most often seen in vinyls bought from supermarkets and similar large chain stores for high prices after the resurgence of vinyl records into the mainstream. Note that this word doesn't apply to old, well loved vinyls. Your grandma's Stones album from college that sounds like it's being played through a wall in present day is well worn. Grummy vinyls already had poor sound quality at manufacture. Generally not a problem if you're not a total audio freak, but those concerned with sound quality find grumminess quite annoying.
I bought a Green Day vinyl from Target for thirty dollars and it sounds super grummy, even after I cleaned it! I'm pretty disappointed, it's hard to find good sounding vinyls in the wild these days.
