insta-lurking 

The act of looking through someone's Instagram account, going past 30 weeks and not liking a single post.

Guy 1; Bro I was looking through this one girls account for 2 hours.
Guy 2; Dude that's intense. Did you like any of her pics?
Guy 1; no way man I was 56 weeks into that shit.

Guy 2; so you were insta-lurking.

Insta-bone

The state in which a sudden and immediate erection arises, so unexpectedly and quickly that chodal whiplash is not uncommon

Boy 1: Dude, how'd you break your nose?
Boy 2: I saw Ellen Henson, damn that woman is so hot that I got a massive insta-bone and it sprung up right in my face.

insta-hater

someone you've just met and make an effort to talk to that takes an instant and intense disliking to you regardless of whether they have an actual reason for doing so (usually combined with glares or snide comments).

I tried to befriend Sam but she was such an insta-hater that she just iced me out before I even talked to her.

Insta troll 

Don’t use insta

Or apps really

Or my phone unless I have to …

Insta …

The troll …

Pretend not of course..

But we both know …

Who you are is less clear of course

Trip trap trip trap

Insta troll synchronising my life …

Even when it’s vague …

Must be coincidence…

insta-gasm 

Giving an instant orgasm by quickly jabbing one's sides near the kidney on one or both sides at once which causes involuntary movement and sometimes unnecessary noises...

Boy 1: I'm going to give that kid an insta-gasm guys...

Boy 2: (After he was given the insta-gasm) (yelling) IT'S SO INSTANT!

Insta-Cum Retraining 

A highly-structured desensitization program designed to reestablish normal sexual stamina after many years of forced, infrequent, dispassionate and time-constrained copulation efforts.

My wife just signed me up for Insta-cum retraining...seems she requires a bit more time and expertise then when we fucked on prom nite...
