Here is a younger Caucasian guy being choke strangled by his larger dominant alpha. He has his bare hands around his throat squeezing the pressure downward and up. These older guys have experience and know how to maximize tongue protrusion based on pressure.

    As you can see the boy is not exaggerating or putting this on - his reactions are based on his anxiety and fear in the moment. This has caused him to open his mouth wide hence more of his tongue protrudes outward. More experience victims have a sharper pointed tongue protruding forward or to the side of the mouth (the fight back response).

    It seems that Caucasian men tend to stick out their tongues moreso than brown men do when being choked or strangled. This is due to the fact that white males have thinner oral tissue and even thinner tongues. This is probably one of the best strangle pics out there.
