Frobnicate, v.: To manipulate or adjust, to tweak. Derived from FROBNITZ. Usually abbreviated to FROB. Thus one has the saying "to frob a frob". See TWEAK and TWIDDLE. Usage: FROB, TWIDDLE, and TWEAK sometimes connote points along a continuum. FROB connotes aimless manipulation; TWIDDLE connotes gross manipulation, often a coarse search for a proper setting; TWEAK connotes fine-tuning. If someone is turning a knob on an oscilloscope, then if he's carefully adjusting it he is probably tweaking it; if he is just turning it but looking at the screen he is probably twiddling it; but if he's just doing it because turning a knob is fun, he's frobbing it.
