When someone (usually a boss) walks around in front of your desk all slow and quiet without saying anything, either because they're afraid to interrupt you or they want to catch you using company resources for personal reasons.
Twisted or contorted out of normal shape or form. Usually used to refer to a style of antique ornamentation or the should-be carcasses of wriggling, horrid eels found laid abreast 'cross the coasts of innsmuth.
Person 1: I'm telling you dude, writhen tendrils are lashing at my door at night.
