Immediate Likeage 

Immediate Likeage (n): When a friend posts a status update, photo, relationship status, etc, and you like it within an embarrassingly short amount of time, marking yourself permanently as some sort of Facebook stalker.

Facebook Newsfeed:

Gina Ferguson and Nicholas Sullivan are in a relationship.

(47 seconds later) Mallory Peterson likes this.

Gina: Good lord. Cool it with the immediate likeage.

Mallory: Sorry, my Facebook stalking threshold is high today.

Likelag 

When you delete a Facebook post or comment you intend to edit before realizing someone already Liked it.

I had a typo in my brilliant status update so I deleted it to repost but because of Likelag, I lost two Likes and one of them was a celebrity. Man, those are the Likes you never get back.
