Instacuck

When someone receives sexual pleasure primarily from someone else's social media pictures - especially Instagram - with or without having any other kind of relationship with that person, especially when the person who the social media account belongs to is openly in a sexual relationship with someone else. Essentially, when someone cuckolds themselves via another person's Instagram.

instacurity

An excessive concern with one’s social media presence, influence, and/or likeability.

I knew I was suffering from instacurity when I strategically timed when I was going to post on Twitter to ensure the most retweets, once even tweeting from a funeral because I didn’t want to miss that “peak” time. I’m sure my late aunt would have understood.
