You need to reorder your logic slightly so that bword is changed as  
soon as the bottle count is decremented:

bottle = 99
bword = 'bottles'
while bottles != 0
	puts(bottles.to_s + bword + " of beer on the wall!")
	puts(bottles.to_s + bword + " of beer!")
	puts("Take one down and pass it around!")
	bottles = bottles - 1
	if bottles == 1
		bword = ' bottle'
	else
		bword = ' bottles'
	end
	puts(bottles.to_s + bword + " of beer on the wall!")
	puts ''
end
