Extend an acts_as plugin

What’s the best way to extend an acts_as plugin?

Specifically I’m trying to implement the acts_as_taggable_on plugin, but
I
want to hide a bunch of methods it exposes and extend a few others.

The extending part was easy. I was overthinking it I guess.

class User < ActiveRecord::Base

acts_as_taggable_on :interests

def tag(*args)
# do whatever
super
end

end
