A crabsnatcher is someone who snatches crabs off
pubic hair, for sport or pleasure.
Could also be a person that has uncanny abilities of diving into water ,
generally with a sandy bottom, and manually yanking crabs from
other peoples crab traps and/ or cutting their crab pot's line so that only they will successfully pull crabs from the water.
That chick he met is nasty; he will be a crabsnatcher before the nights over.
The crabsnatcher ruined everyones
fishing...i assume it was the guy in
scuba gear that came up with a bunch of crabs, despite having no crab pot.
