Tone-er; noun; An erection sustained upon the hearing of auditory guitar tone wonder (i.e Neal Schon, Lincoln Brewster, David Gilmour, Shawn Lane, Eric Johnson, Andy Wood, Blues Saraceno, Phil Collen, etc.). Exclusive to guitar players who actually know what the fuck is up.
Ex: "Dude, I was listening to some Steve Perry solo work in math the other day, Lincoln Brewster's solo on "You Better Wait" totally gave me a tone-er, and I was sitting next to that hot Russian chick." "Ouch, at least you weren't listening to Metallica."
