RAS is the abbreviation for "Resilience Against Sex".

A passive skill possessed by your girlfriend or spouse that procs (programmed random occurrence) at the most undesirable times. When RAS is triggered, synapses fire to their brain to prevent coitus at all costs. It is also, frustratingly, the most effective form of contraceptive being 99.99% effective, when used properly.

This skill synergies well with "I'm tired" which increases the proc chance from 0 to 100%. There are currently no known items to remove this debuff/curse.
Girl: Doctor I keep forgetting to take my BC pills on time and I'm too nervous about an IUD insertion, what are other contraceptive options?

Doctor: Child, let me teach you the passive skill called RAS.

Guy1: So, Valentine's day, you gonna smash her tonight?
Guy2: Bro, Valentine's day does not magically cure RAS.

RAS is the english version of the Korean inside joke in I-LAND (now debut group ENHYPEN).
In Korean, the word RAS in romanised Korean is "wonbunsu".
RAS meaning: Resentment, Anger and Shame.

This joke started from I-LAND trainee, Jay, when in episode 2 of I-LAND he kept on raising his hand for a part, and that was until he got part 8.
Jay has many RAS moments ,from episode 2 of I-LAND, the scene of picking parts embarrassing himself, to episode 7 of I-LAND, crying because 6 trainees from the I-LAND had to move down to the GROUND.

This inside joke is very popular among the trainees. In episode 11, part 2 of I-LAND they were giving roles for who was going to do what for cleaning. Heeseung (another trainee that ended up debuting in ENHPYEN) recommended Jay to wipe the windows because of his RAS moment in episode 7 of I-LAND part 1.

*In the conversation below Eggie is the fandom name for people who watched I-LAND. An egg was one of the main structures in the I-LAND.
Jay: I have so many RAS moments.
New eggie: RAS? What is that?
Jay: Resentment, anger, shame. Technically, regret. For example in that one episode I cried when trainees were leaving the I-LAND. I don't think I looked too good. Especially with Jungwon (another trainee that ended up debuting in ENHYPEN) next to me looking so beautiful even when crying.

Real As Shit. If you're RAS, you're someone who's not to be messed with. Those who're RAS have a big ego and sometimes a hard/big head.

Repulsive Asshole Syndrom- a syndrome common to PMS, yet taken up by the male species. Unlike PMS, RAS has the potential to last longer than one week and can affect a male individual on a daily basis. This syndrome is commonly manifested in short, hairy, North Shore, Greek boys who like to play with girl’s hearts and rip them out.
Roberta: Zev stopped texting me and ignored me at the party. He’s being a real jerk.
Jules: Don’t worry Roberta. This happened to me and Eli last week. Zev probably has a bad case of RAS.
