Tuesday night's "sonic boom" over Myrtle Beach was
caused by military jets, not Geminid bolides:

Jure, Roberto, and all,

     Looks like I made a good call...the military
confirmed that cold conditions caused two of their
fighter craft to have extended-range sonic booms that
would have occurred right at the time the sounds were
heard (inland).
No Geminids at fault here....

Taurids produce sonic booms, there is (was?) an audio
file on IMO FIDAC site of a sonic boom produced by a
-10 Taurid fireball.
I'm not sure about the composition of Taurid
meteoroids - cometary material only or perhaps also
some denser material as, IIRC, there are also several
asteroids associated with the stream? Assuming greater
density also corresponds to greater strength,
I see no reason why large Geminid meteoroids couldn't
penetrate low enough in the atmosphere to produce a
sonic boom.
As for what the people heard, you're most probably
right.
