In linguistics, the labiodental allophone is formed when the upper teeth (the dental) meet the lower lip (the labio). The sound produced in English can be a voiced R (say “Row") or a voiceless F (say “Fred.) If you take a look at the labiodental formed by Tiger Woods as he smashes his cap into the fringe (another voiceless fricative), I think you’ll agree that he exclaims “Fellowship” or “Frolic” or some other clever phrase. After all, it was one fricativeing putt!
EDITOR’S NOTE: The /r/ could be a labiodental approximant, alveolar, postalveolar or a retroflex approximant, depending on your taste.

alveolar approximant (sometimes retroflex). And /f/ is not an allophone in English, it's a phoneme. However, you are right about the sound that Tiger is making in this pic.
articulator, ie, it's not where the air is
restricted in the production of the phoneme.
Download Praat, record it both ways, and take a look at the first and second formants of the sound spectrograph. They should be identical (unless you've got an atypical speech impediment).
I've often wondered why so very few people read/comment on your posts (both of you), and this clears it up considerably.
No, BV, I do believe he was expounding on a biter.
