Instavomit 

Verb: When you smell or see something so terrible you vomit immediately.

I was at Ricks yesterday when this big ugly guy walked in and he smelled so bad I almost instavomit.

Instamosity 

NOUN
Basically the idea that Instagram creates a lot of animosity in our real lives.
Can be used with other social media’s as well, but keeps the insta root/prefix.

Animosity is strong hostility.

All credit to Sean Kilny and Taylor Strecker.

“He never posts me on his insta, that hoe’s just got me filed with instamosity”
