feet board 

usually known as skateboard... but because of the fingerboards, evolving into a handboards, i think handboards will evolve into a feetboard where you can use your feet to play.

i'm a fucking feetboarder! what is a skateboard?

fretboard 

The long area of the guitar under the strings where the player applies pressure with his or her non-strumming in order to produce different notes; the long, flat area on the front of a guitar neck

Wow, that guitar player is fast! His fingers were really flying up and down the fretboard.

feetboarding

Performing skateboard like tricks and grinds with nothing but regular (non-soap) shoes.

You like that feetboarding? I just landed a backslide grind.

Fretboard Diarrhea Syndrome 

Fretboard Diarrhea Syndrome (FDS) afflicts thousands of guitar players. This condition causes the guitarist to play way too many notes and play them way too fast. This style of playing in no way serves the melody, the song, or the singer...it only lets the guitarist show off and gives him a chance to bob his head like a rock star. This unnecessary and distracting barrage of notes is often delivered at way too high a volume also, further diminishing the value of the playing.

There seems to be no cure for FDS.

"That new guitar player in the band? He has a severe case of Fretboard Diarrhea Syndrome...he, and now that band, is unlistenable!"
