I don't usually hang out here, just once in a blue moon.

A Kevin Moon stan

A Kevin Moon Stan (aka a Moonlight)is a Kevin Moon Enthusiast who absolutely ADORES KEVIN. They always talk about how amazing and talented he is. Their search history is most likely just filled with “Kevin Moon’s arms” and “Why is Kevin so hot?”. Whenever there is a post or a video about Kevin Moon JUST KNOW THAT THEY MOST LIKELY WILL ALREADY BE THE COMMENT SECTIONS SIMPING FOR KEVIN AND PRASING HIM. Kevin Stans are most likely to have Kevin in their username, or as their pfp, or probably something related to Kevin in their bio.( For example @kevinsupremacy on TikTok)

Person 1: “omg @kevinsupremacy on TikTok is a Kevin moon Stan!!”
Person 2: “WOWOWOW NO ONE IS A BIGGER KEVIN MOON STAN THAN KEVINSUPRENACY”

once in a purple moon

An extremely rare occurrence, rarer than 'once in a blue moon'.

A particular team winning the championship happens once in a purple moon. A total solar eclipse seen from Europe happens once in a purple moon.

Hotter then wolf pussy on a full moon

A response to an increase in temperature; or being in the presence of a multitude of police officers.

Turn on the air conditioning, it is hotter then wolf pussy on a full moon in here.

Peek-a-boo Moon

The act of placing ones ass cheeks against a glass door, pushing a turd out just enough to kiss the glass and pulling it back in. Usually performed at bachelor parties, random hotel room where pool guests can see etc.

Holy shit did you see that guy shoot the old couple the peek-a-boo moon when they walked by.
