NSFL

Not Safe For Life. Stuff that isn’t appropriate no matter where you are, how old you are, or what time it is. NSFL content is usually gore. Examples of NSFL content include: Goatse, kekma.ga, a lot of videos on Liveleak, 1 Guy 1 Jar, 2 Guys 1 Hammer, etc.

I was on an NSFL content binge last night because I was bored and I had morbid curiosity. I was extremely traumatized and couldn’t sleep at all

(NSFYM) Not Safe for Your Mom

A word, phrase or thought that is likely to embarrass, fluster or even cause a mother to cry

Ed: I want to post to Twitter, but your mom follows me and this comment is definitely NSFYM.

Andy: NSFYM? And why does my mom follow you?

Ed: Yeah, (NSFYM) Not Safe for Your Mom. And, um, can you repeat the second question...

NSFYE

An acronym that stands for "Not Safe For Your Ears".

As one example, you may use this acronym on YouTube when your video contains an audio (sound) component that some viewers may find distasteful, such as heavy metal music like Anthrax or Megadeth.

{in the YouTube description of a video I made and uploaded myself}:

*NSFYE* (Not Safe For Your Ears). A video of the Syma S107G R/C Coaxial Helicopter flying in my room, set to another Anthrax song.
Abort this video immediately if you find thrash metal music distasteful.

That music you hear is the song "Howling Furies" by Anthrax. This heli is not sound-sensitive; the audio may safely be ignored or even muted if it pisses you off.

NSFL

Basically, NSFL means “not safe for life”. It’s when something is so scarring that even Satan himself would fear it. A lot of Bait-And-Switch sites use NSFL content for “a joke” when it’s really not. Some of these Bait-And-Switch include, but are not limited to: kekma.ga, dance.swf ,womansalliance.xyz and so on. Those are just some examples

User 1: Hey, Mike! You should check out (bait and switch site)! It’s so cool!

User 2: First, how do you know my name, and second, I’m not clicking that link.

User 1: Just click it!

User 2: Ok, fine. (clicks it) WHAT IN THE LIVING FUC~!

Moral: Don’t click on random links. It could be one of those NSFL sites.
