when a girl plays you like a piano

the act of playing piano. although not a formal term such as practice or perform, the term pianoing is specific to having a damn good time playing the piano, regardless of it's practice or performance.

The best instrument in the world. Best played with Chopin or Grieg. Most fun to play with candles burning while it's storming outside.

playing piano in a non-toss-giving way, e.g no scales or similar crapola, just ninjaing the ivories in the lecture theatre at lunch
method for attracting crumpet that attractive but non-musical dudes can't do

Better than a guitar

The best musical instrument ever! Used to make beautiful music... and waste hours of the day on.

When your voice goes all glitchy and weird when talking on a voice chat.
