The "brow" social is dead and buried, and the raise social has been
changed. You now have to:

  raise			# raise hand
  raise hand		# also raise hand
  raise hands		# raise both hands
  raise eyebrow		# raise one eyebrow
  raise eyebrows        # raise both eyebrows

PS. Yes, what you before could write "bro" is now 1 character longer:
"ra e".
