Instablock

To block a user (of an internet service, often Instagram) without a moment of thought because of the egregiousness of their words.

Clearly that guy is an obvious troll. I didn't pause a second to instablock him.

Instablast 

1) v. to "like" every image in one's Instagram feed in a single, continuous session without regard for the quality of or interest in the content.

2) v. slang term used by millennials to describe a sex act by a male who prematurely ejaculates.

It took me forty-five minutes to Instablast, since I hadn't looked at my Instagram account in several days.

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!
