Here are some names of techniques, you'll know some of them for sure:
tapping: using the picking hand to fret notes, playing hammer ons, pull offs with the "wrong" hand.
Pick tapping: hammering the string with edge of a pick, e.g. as in Satriani's Surfing with the Alien.
Squeal = a harmonic. Often combined with a bend or whammy bar stunt.
Pinch harmonic: Brushing the edge of a string using the side of your thumb keeps part of the string from moving resulting in a harmonic. Called "pinch" from the sort of pinching action.
Harp harmonic: The right hand thumb picks a note while the 1st finger of that hand briefly and lightly touches part of the string to make a harmonic.
Touch harmonic: the tip of a finger is brought forcibly into contact with a string sounding a harmonic. Alternatively a note can be pulled off and another finger present at a harmonic node starts a harmonic, most easily done combined with tapping.
Artificial harmonic: a harmonic where the left hand frets a note on the string concerned.
Natural harmonic: a harmonic where the string is open.

Prebend: A note is bent up without playing it and, once bent, played. This note can then be unbent. Useful if you dont' have a whammy bar or if there's some other string sounding which you don't want to alter the sound of by diving a whammy. Very tough.
Unison bend: two or more strings are fretted and one or more of these are bended. Hard to do this properly, Roy Buchanan could bend one string one tone and another a half tone at the same time. That's talent...
Oblique bend: One note is prebent, then two are plucked, the bend released and another note bent up simultaneously. Possibly the toughest functional technique I know of.
Violining,AKA volume swell.
The string is picked with the volume down and the little finger, curled around the volume pot, swells the volume. This cuts off the initial "attack" of the note making a smooth sound. Sounds great with a bit of delay or reverb.
Tiger purr.
A floydd rose type trem makes this cool purring sound if you pull it away from the strings and let it snap back quickly.
If I couldn't laugh at myself how could I laugh at someone less ridiculous?
