instabust 

Upon seeing a chick so hot, you instantaneously cream your pants. It's like a super-fast wet dream, but awake and in public. Often used in hyperbole since guys don't actually do this, except lame-ass premies.

Guy: Dude, did you see how tight that chick's ass was?

Guy 2: Yeah man. I just instabusted.

************************************

*As you pass a hot girl*

Dude: Instabust!

Instacunt 

A woman who's emotions turn from happy (or at least normal) to raging cunt in the blink of an eye for no apparent or good reason.

I was minding my own business when she turned instacunt on me.

We were getting along just fine, when all of a sudden she went instacunt on me and told me to get the fuck out.

InstaBitch

A person on Instagram who is only interested in their own follower gain. Usually narcissistic teenage girls who secretly think they'll be the next Kylie Jenner.

Jane: I'm gonna follow this fake whore so she'll follow me, then I'll unfollow her and hope that dumb bitch doesn't find out.

Jane is the example of an Instabitch.
