immediate fear 

It's when you think you could do something, then immediately realise how much you lack confidence to do it

"I thought I could do it man, but then, I was stuck with immediate fear"

effective immediately 

Basically it means, you do this shit right now or you suffer the punitive consequences!

Also, do wtf I said and do it right now.

The following expectations are non-negotiable. Effective immediately. Please advise.

Immediate Likeage 

Immediate Likeage (n): When a friend posts a status update, photo, relationship status, etc, and you like it within an embarrassingly short amount of time, marking yourself permanently as some sort of Facebook stalker.

Facebook Newsfeed:

Gina Ferguson and Nicholas Sullivan are in a relationship.

(47 seconds later) Mallory Peterson likes this.

Gina: Good lord. Cool it with the immediate likeage.

Mallory: Sorry, my Facebook stalking threshold is high today.

Return my calls immediately 

Something people say in an email when they’re mad at a company and they think that ordering them to do something is going to make them do it as if they are their bitch.

*Reading: “We have tried to contact you and there has been no answer. Return my calls immediately at (phone number).”
Hm, I was going to call her back until that bitch command. I’ll consider calling her back next week.

immediate gratification 

Someone who expects you to drop everything you're doing, to cater to their bullshit needs. They feel what they need you to do is more important than anything you could possibly be doing. Most are selfish assholes with zero consideration for anyone but themselves. Plus, chances are they haven't even tried to do it themselves and are just too damn lazy and inconsiderate to try.

If a child exhibits immediate gratification when asking for something, their sense of entitlement will grow worse with age. Never just jump up to do what is asked of you, make the person or child waits until you are done with what you are doing, showing that your time is just as
important as theirs.
