Subject: how to refactor these code?

def ss(s = 'hello', yeah = nil)
  if yeah
    puts "something"
  else
    puts "other thing"
  end

  #code continue ....
end

I have this method, use it like that:

ss('hi', yeah = true)
ss('hello')
ss('fuck', yeah = true)
ss('hello',yeah = true)

very ugly.. sometimes I just need to passed yeah = true, but I have to
added 'hello' first.

what should I do?
