what 's the meaning of " worm guys" and " whim guys " and " brackety " ?

what 's the meaning of " I cannot feel my legs" here ?

thank you !

[Scene: Ross's Apartment, the guys are there assembling furniture.]

Ross: (squatting and reading the instructions) I'm supposed to attach a brackety thing to the side things, using a bunch of these little worm guys. I have no brackety thing, I see no whim guys whatsoever and- I cannot feel my legs.
