Add text "Share products to your friends" above of share icons

Hello,

I'm using WooCommerce for my site. I'd like to add the text "Share products to your friend" at above of share icons like this screenshot http://screencast.com/t/oX5tDQoB

After some searching, i found this file has the share icons code, i'm not sure it's belong to theme file or WooCommerce file and what is the code (share product text) i need to add to.

Could you help me take a look? (you can use grant access if you wish)

Thank you,
Tuan.
