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.

"As a popular dominatrix, I have dozens of men every day admit to being my instacucks!"

Instacock

When a person's Instagram photo is so attractive, it gives you a semi-erection, one that's enough for you to question your existence and wonder why you'll never get with someone like that.

Dude: "Hey, man did you see (insert attractive person's name here)'s picture on Instagram? "

Other dude: "Ugh. Yes, dude. It gave me Instacock."
