Ok I understand it now, the better way to do it is to edit your header.php and look for bloginfo( 'description' ) then change it with custom_get_bloginfo() then add you can use this to your function.php

function custom_get_bloginfo(){
switch( $show ) {
case 'description':
$output = "my description";
break;

default:
$output = get_option('blogname');
break; 
}
return $output;
}
