Insta-liked

Mainly used as a comment for the social networking site Facebook, or the video sharing site YouTube. If you come across a page (on Facebook) or a video (on YouTube), and as soon as you see it, you are instantly overcome with the urge to "like" whatever it is, you "insta-liked" it! See what I did there? :)

"OMG this page is awesome, I totally insta-liked it!
