The modern version of hieroglyphics: what documents look like when they have been scrambled by file-transfer, for example, when email attachments open up as a chaos of hypertext markup, webdings, and ther bits of symbolic junk. What code looks like to technophobes. Can be used to refer to nonsense more generally speaking. A useful claim for excusing your failure to attend to tasks.
I tried to process up your invoice, but the attachment came out as hyperglyphics.
