jaw dislocate

“...You’re dead.”
A roar reverberated through the dark street.
It only took an instant.
Accelerator reached his arm in through the opening the windshield had previously been
in. His slender arm headed straight for the face of that man in black as if it was being
sucked in. More specifically, it headed for his mouth. He jammed the four fingers minus
the thumb of that hand into the man’s mouth. His white hand broke straight through
the black knife-proof mask and went straight to the back of the man’s throat. The thumb
reached around below the man’s chin.
He then pulled his arm back.
With a cracking noise, the man’s jaw was dislocated.
“Ah ha ha gyah ha ah ha ha ha hee hee hee gyah ha ha ah ha ah ha ah ha ha ha ha!!”
With an explosive laugh, Accelerator pulled the man’s body out of the driver’s seat like
he was catching a giant tuna with a single fishing pole. He then threw the man behind
him. The man in black flew straight over the sidewalk and slammed into the shutter of
the multi-tenant building.
This created a great noise like the crash of lightning.
