buffer flushThe transfer of data from memory (RAM) to storage. Whenever a document is saved, the program writes the contents of a reserved area of memory to the hard disk or SSD (it flushes its buffer). See buffer overflow and buffering.
Go Flush Your Cold Buffer!
Try this on your colleagues. Tell them to "go flush their cold buffers!" A cold buffer is a memory area that either contains stale data or unsaved data (not yet flushed).
Better yet, say "go flush your cold buffer into your SCSI DASD" ("scuz-ee daz-dee"), which means "save the data to the SCSI drive." SCSI drives are not as common as SATA drives today, but so what... the most important thing is that you say this without cracking a smile. The more technical your colleagues, the more puzzled their reactions. See SCSI and DASD.
