"...I take pleasure in the details. You know... a quarter-pounder with cheese, the sky about ten minutes before it starts to rain, the moment where your laughter becomes a cackle... and I sit back and I smoke my Camel Straights and I ride my own melt" (Troy Dyer, "Reality Bites", the movie)
I'm often told that i'm doing everything totally wrong, that i'm a loser. I simply say I'm riding my own melt.
ride one's own melt
