Used in front of numa, which is Japanese for swamp, in the pre-grunge band Spluii Numa. Spluii, however, has no meaning, and can mean anything, or just be and interjection. Many people have also told me that it sounds like an ejaculation word.
"Dude, you got spluii all over my carpet"
(while jumping of roof)
"SPLUIII!!!!!!!!"
