Should i use _n for pronouns in translation?

I use _x() now! I accepted the answer just because he understood right and was first. So don’t get confused!

$like_me_on = __('Like me on %s', 'my-plugin');
$like_us_on = __('Like us on %s', 'my-plugin');

$follow_me_on = __('Follow me on %s', 'my-plugin');
$follow_us_on = __('Follow us on %s', 'my-plugin');

$my_x_profile = __('My %s profile', 'my-plugin');
$our_x_profile = __('Our %s profile', 'my-plugin');

I have this code and i read about _n() and saw only examples with $count on wordpress codex.

The text is for a bunch of social services that will later be %s, if i would use _n then i would have this variables combined, but the translation string would be more complicated to read. So what is best practice and is this intended for pronouns or just for numbers?

It’s interesting idea and I think that such approach will work for you. What I would recommend you is that it will be better to use constructions like this:

// $singular = 1 - for 'me', 2 - for 'us'
$like_on = _n('Like me on %s', 'Like us on %s', $singular, 'my-plugin');

In this case it will be easier to understand how to translate the phrase.
