The act of searching the
floor for stray pieces of methamphetamine, typically for an hour or longer. This is in part because it's almost
always picking through carpet for near-
shake. Never involves actual shards or fingers, despite the name, because larger pieces are so much more quickly and easily found.
The effects of meth leads tweakers to compulsively do this, enough that it is a strong indicator of being twacked -- or much less commonly spun out (the sleep deprivation-induced fatigue and the distractability caused by it typically prevent getting stuck for long).
Notably, no
ice needs to have actually been dropped -- if they believe some
may have been, that is often enough for the search to begin -- and the search
will frequently continue whether everything has been found, there never was anything, or all that remains is particles that only a vacuum could extract from the fabric (the last
will involve copious cursing and, if no one manages to redirect the seekers' attention, possibly lead to some expression of
rage).
Man, he was so twacked last night; he was
shard farming the whole time I was over there.
Hey, you remember when we
spent like four hours shard farming in that hotel when you dropped the
sack?
