Facebook Commentathon 

An endless, and often boring list of comments made by a number of friends over a number of days, often resulting in posts over 50 times the average quota of a Facebook post that invariably veer miles away from the initial postee's post.

Pete: Had the best night eva with Sammy D and co - yeah man, you guy's fucking rock!
(100 posts later ...)
Eddie: I think elephants really have amaaaaaaaaaazing memories and shit. And wtf is with the Facebook Commentathon dude?

-My Fiancee, her cousin and myself had a dumb commentsation on my fiancee's picture on Facebook that wasnt even relating to the picture.

-I have 64 comments from the same person because we decided to have a commentsation and now everyone can read what we were talking about.

Commentsation 

The act of having a whole conversation using comments. When two or more people feel it's necessary to use the comment section of a photo or video on Youtube, Facebook or otherwise social network instead of just calling one another or using a chat platform.

-That's a nice picture.
-Thank you! How are things Jason?
-Very well. I recently saw you on grandma's album of photographs kissing the dog.
-Oh yes I remember! How is she?
and so the commentsation continues.
