Flap, in (archaic) computer science jargon, refers to the process for unmounting a magnetic tape. When the system operator commanded a tape drive to unmount a tape, it would rewind the medium and then, as the tape unwrapped from the take-up reel, it would go "flap-flap-flap" as the feed reel spun down. Thus the term.
