Entry: fulgurant (adj.)
In context: "Lightning claws the eastern sky, and it's neat in the weight room's dark because Lyle is in a slgihtly different position and forward angle each time he's illuminated through the window up over the grip/wrist/forearm machines to his left, so it looks like there are different Lyles at different fulgurant moments."
Definition: Flashing like lightning.
Other: I sometimes wonder if just every once in a while DFW wrote a sentence simply to use a particular word. I don't think I could resist.
