Rotten pussy. Originates from the video game Elden Ring, where a boss called Malenia proceeds to get naked to show off her rotten pussy and beats the shit out of you at the same time.
State of being. Something/ a situation/ a place/ a person / a feeling that is a so specific, so niche and so unique that there is no other way to explain it other than it being RALUSSY. Not everyone or everything can be ralussy, it is only for the select few to experience this feeling of ralussy.
Bro last night was so ralussy (we blacked out and did something insane)
