wow and flutter 

Speed variations in a turntable,phonograph, or cassette player that cause irritating flattening in pitch with sour notes (wow) and/or garbled notes with jerky sharpening in pitch (flutter). Often heard from poorly manufactured, old, or poorly-maintained audio equipment. In the ages when LPs and audio cassettes were the only audio media available, stereo/high-fidelity magazines often used to rate audio components with wow and flutter specifications ranking at the top of the list.

George, your turntable has some nasty wow and flutter. The music sounds sour. It looks like it needs a new belt around the platter.

Refers to da "verbally-gushing 'n' eyelash-battingly-impressed" reaction of cute chicks when you show them how well your magnetic-tape-based recording/playback equipment works at producing great stable-speed sound.

Since most high-end audio-systems have gone digital nowadays, you may have to find other ways to make da ladies wow and flutter over your recording-studio equipment's awesome sound-capabilities.
