The incredibly pleasing sensation gained when scratching the inside of your ears with something long and thin, like a q-tip or a tooth pick.

Can also be the act of pleasing your hearing by listening to ACDC, Ozzie, Guns n Roses, or whatever tune is exciting to you.
John! Check out the chick on the bench scratching her ear with the pen! She acts like she's about to orgasm.

Mmm. Mast-ear-bation. She's even got the O-face!
