I am going to have to admit that my phrase, the "BIG KAHUNA," that in which I tend to write under most of my posts, well..... its pretty exciting to see that its getting so much attention. This post all started for simple questions about who, why, what, when, & how. Like I have said many of times before, here the phrase goes, "Big Kahuna," the big one, head poncho, the boss. When I say it, I say it as catch the biggest one out there.

Either my phrase will catch on to the rest of you, or this topic has gone way to far.

I think that some how it deserves its own smilie now.

Yeah, man. You are a regular legend now! Thanks for bringing a totally unique and previously unknown expression to the forum!
