When you stick your tongue outside of your mouth and gently blow, it makes a common sound to indicate "whatever!" or "I don't like your answer/response" or "Yes, you are smarter than I am."

What is the name of this sound and how do you spell the sound?

    See blowing a raspberry on Wikipedia, which says the sound can be transcribed in IPA as the unvoiced linguolabial trill [r̼̊], and is "commonly spelled" pbbbt on the internet. – Dan Bron Jan 28 '15 at 22:34

    Bill the Cat "spells" it "Thbbft" (and possibly other ways). – Paused until further notice. Jan 28 '15 at 22:52

    @DanBron Interesting. When I see pbbbt, my immediate reaction is to interpret it as representing [ʙ̯ː] (an unvoiced bilabial trill or what is also often spelt as pfffft when indicating indifference, or prrrr when indicating a horse neighing). – Janus Bahs Jacquet Jan 28 '15 at 23:10

    "Yes, a raspberry is a 'wet' sound made with by blowing air through wet lips 'blocked' by the tongue. Whereas, a 'pffffttt' is made by forcing air through a (dry) lower lip and front teeth." – 5arx What's the verb for making that “pffft” sound? – Mazura Jun 6 '16 at 22:00

I wonder what the linguists will make of this question.

It sounds as though you are describing what is colloquially known as 'Blowing a Rasberry'.

As to how you would represent it in writing, I'm a bit flummoxed. Experiment with the following (all as long or short as you wish);



Much better than the internet Pbbt. You could have started something here.

I believe the word you are looking for is "pfft", defined as:

An expression of a lack of interest in another persons comment

Blowing a raspberry is something different, and noticeably more insulting.

    The OP specifically mentioned poking your tongue out, which makes me think this is a raspberry, and not a 'pfft'. – dwjohnston Apr 8 '16 at 0:37
