18s 

18 inch subs, commonly placed in a car's trunk for that extra BUMP BUMP

"18s in tha trunk, didn't see no wires, then i heard BOOM from the amplifiers"

The 3/18s 

The temporary gastroenterological condition of producing green stool, often occurring the day after drinking vast amounts of green beer on St. Patrick's day.

Those green-colored Christmas treats gave me a terrific case of the 3/18s.

18saisai 

A TikTok account who mainly posts about Kurapika from Hunter x Hunter. Her favorite hobby is looking at pictures of Leopika clocks creating a false hope she might obtain one some day. Other interests of Sai include of dhar man.

Sai is a smoll bean, but don’t be fooled by her “cutesy” persona. She’s actually extremely hostile. Sai is the embodiment of true evil because she won’t laugh at a certain extremely awesome and funny TikToker’s videos. Many of her fans head canon her as ginger.

Some of Sai’s likes are Smol, Kawaii, anome girl, and Bakugo kins. Some of Sai’s dislikes include of gingers, country girls, Vada, and blondes.

18saisai Is so emo! I can feel the darkness of her soul.

18saisai’s videos are cuter than a daisy on a fresh Sunday morning!
