1) Put your method definition in a module:

module M
   def my_class_method
       # do something
   end
end

2) extend your class object with your module

class A
   extend M
end

3) use your methods from M

class A
   my_class_method
end

Of course you can combine 2 and 3:

class A
   extend M
   my_class_method
end
