Sir Spanks-a-lot confidently deleted the recently downloaded Young-Dum and Full of Cum.mpg #5c, starring Aurora Snow, as his pornographic memory informed him that it was already stored on his computer's hard drive; cluster#: 43,600; sector# 165; Size: 133,455,000 bytes, et al.
I started saying this about 20 years ago to make the girl's laugh. It's pretty self explanatory. Use it instead of photo. It's one of those words people look back at you, like "did he just say that?".
A person blessed with a Phonographic Memory has the ability to instantly recall and name the origin of sounds, chords, bass lines, drum fills, and guitar licks from the records he/she/they heard in their youth. Everybody recognizes the opening licks of "Satisfaction", but a person with Phonographic Memory "...can name that song in one note."
It is not the hearing of a train whistle and being reminded of the long summer evenings in Iowa. It is not recognizing a song being played faintly in the background of a Budweiser commercial. It is directly related to the graphic recording ( the LP or 45 rpm record, quite likely ) of those particular notes, and a instantaneous and pinpoint recognition of the song. Phonographic Memory (PM) is like muscle memory, as it is developed by repetition.
We gotta getCarlos on our team for this Trivia competition. The dude knows every song ever recorded! All he needs to hear is one note, and he can name it. He has Phonographic Memory!
