A zerbert. Because that's what they called it on the Cosby Show. I think.

In Australia that is known as a "raspberry", not that anybody alive knows why.

I was always under the impression that it's called a "zigbot".

Michael Jackson's best pick-up technique?

We used to call them phooey kisses!

I think "fffpppt" is probably the most descriptive term, although I vaguely recall it referred to sometime in my early childhood as a "belly burp". But then, I spent my early childhood in Cleveland, Ohio, so YMMV. (And NO thanks for bringing back repressed childhood memories...)

My boyfriend thinks it's called a raspberry, but I thought a raspberry was when you made that noise just be blowing your tongue, with no belly involvement. It's the same noise though, so I'm willing to term it a "belly raspberry".

I'm going to second the zerbert (I always wrote it as "zrrbrrt" to try and mimic the sound). As soon as I began reading your description, I thought, "He's asking about that thing from The Cosby Show!"

I provide tercerary support to the 'zerbert' line, as I specifically remember this on an episode of Cosby.

I provide quadratic support for "zerbert." But if you do it to a female, is it "sherbert?" Or is that just silly?

I remember rasberry as the proper term, though lets bend and strech this and call it a 'rasbery sorbet" and call it all off?

Or we could call it a Raspberry Beret, have our Purple Rain phase and rename ourselves to an unpronounceable symbol. That would be fun.

"Zerbert" was definitely the Cosby Show name for it, so much so that it almost pushed the other name I know it by out of my head. For some strange reason (probably the same reason that my family always referred to macaroni and beef in a tomato sauce as "hoofgapoodle", even though the same dish in the Mark Twain High School cafeteria was called "goulash"), we always called it "foofing". Other variants were "I got foofed", "I'm going to foof you", etc.

Razzberries.
And the schnozzberries taste like schnozzberries.

I saw the term "hoovering" for something perhaps similar, and I thought of your post. Blowing a raspberry is mainly exhaling through pursed lips, its not necessarily making contact with another persons body (IMHO).

A "flerble." And the verb is "to flerble." I can still get my seven-year-old to run screaming and giggling delightedly around the house by simply wondering aloud if at the moment anyone needs any flerbling (a practice he's endured in gleeful agony since infancy).

Our babysitter imported the word; I don't know where she got it.

I'm in Massachusetts, in case you're tracking regional variations.

Just dropped into your blog randomly. Love it. Blogrolling it.

I have called it "blowing a raspberry" because that's what I've always heard it called.

(Brad - early alert, I may be in St. Louis the 2nd weekend of October. Don't you dare be out of town!)

Zerbert. From, as so many have already pointed out, the Cosby show.

Thank god I'm not the only one.

My Pennsylvania Dutch relatives call it a zuber (zoo-ber). And, Brad, as you suggested, you don't have to outgrow them!

We called them ferberts before Cosby, zerberts after. Don't know where the /f/ came from.

I will affirm "Zerbert" because a former girlfriend did that to her 1-year-old son and this was the appellation she used. Does anyone know how to reach Mr. Brad via e-mail so as to procure an invite to the ca-bash on Friday (3/12) evening?

I agree that it's a zerbert 100% none of this raspberry nonsense! My sisters and I called them zerberts since we were little and would argue constantly over the name with friends and one day the Cosby Show verified our term. I'm having this argument with my boyfriend right now. Show the zerbert some love ::smile::
