Eargasm

That good sensation you experience when you are listen to good music.

You find yourself sitting on a couch in a club, bobbing your head with eyes closed. Makes you feel light headed, as if you are floating.

Piet: Dude, what are you listening to on those head phones that's making you smile?
Gertjie: He can't hear you Piet, he's having an eargasm, it must be a nice jam on his ears (pun not intended).
