habitué\huh-BICH-oo-ey\ , noun;
1. One who frequents a particular place, especially a place offering a specific pleasurable activity.
I am familiar with this word, although it's not one I often use. Reading the definition, I thought "that describes my loyal readers of this blog!" but then I saw the rest: "... especially a place offering a specific pleasurable activity." No, I don't think it's pleasure they're seeking here, but it's more like a train wreck - a horrible sight, but they just can't tear their eyes away.
