Instafight 

A fight between two or more people on Instagram. The comments can be seen by everyone. No one knows exactly who is watching the fight. If there are more than three people involved it becomes an Instabrawl.

Geoff and Stephanie were having an Instafight so I jumped in to try to break it up.

When a person, usually a female, uploads pictures of herself to Instagram and then makes self-deprecating comments in order to get compliments. She is likely to describe herself as "grungy" and point out that she is not wearing make-up. This behavior also occurs on Facebook and Twitter.

When Mary saw Lindsey's latest Instagram picture of herself, complete with "no makeup" and "grunge" hashtags, she decided to unfollow and avoid future Instafishing.
