NTR is netorare or when your partner is having sex with someone else either by coercion, force, or deception, and you either know and can't do shit about it, or don't know
Cuck(olding/oldery) is your partner having your permission to have sex with someone else, and you get off to it
Cheating is when your partner is being unfaithful to you and you're unaware of it
Simping used to be just shorthand for simpleton, or a dumbass who plays along with someone else's ploy
