Yitzy

The ability to play guitar so quietly that no one can actually hear you. Often, but not always, this magical ability will result in a yellow toaster.

Yitzy can also be defined as one possessing the moral and spiritual capacity to compose harmonious melodies often involving Pellow, Eric, or suicide.

"Wow that guitarist looks awesome but I can't hear anything"
"Yup, thats a classic Yitzy"

or

"Pellow, such a merry fellow"
