A turd that is solid and long. It will be tapered at both ends, like a large joint. These usually leave a clean first wipe when performed well and may require more than one flush to get it down Mr Toilet Bowl's hole. These are ideal, friendly turds. A shitter's best friend.
I ate 7 meals yesterday and as soon as I woke up, a Big Kahuna was begging to be released. I shat it out and praised god for his wonderful mercy.

Get the Big Kahuna mug.
A rude, malicious, tyrannical person who took advantage of Natural Selection's best modder (see wordVoogru/word). Was known to use cheats that was accidentally implemented into NSAdmin. In the end, he was ousted by Voogru and the community of voogru.com. Upon his ousting, he deliberately stooped to the intelligence level capable of a 3rd grader, using ban threats, IRC insults, and even threatening to call the FBI on people in false accusations.

Commonly seen with lapdogs kittymor and Landshark, and his prepubescent idiot of a son, Prince Kahuna.

Also seen in urbandictionary.com making up false stories so bad, the critics want to hold a .357 to their head screaming "END IT NOW!"

Synonyms: wordasshat/word
