two bones twisting in tandem so your hand can flip the bird in any direction
means The part of your arm between the elbow and the wrist, housing the two bones (radius and ulna) that let your hand rotate.
from A plain Old English compound: 'fore-' meaning 'in front of' or 'before,' bolted onto 'arm' (Old English 'earm,' a cousin of German 'Arm' and ultimately tied to roots meaning 'joint' or 'fitting together'). So it's literally the 'front arm' — the forward stretch of limb that comes before the hand. The same 'fore-' shows up in forehead, foreground, and forewarn, always pointing to what sits ahead.
