Crabby

I'm feeling crabby.

Tom has been really crabby today.

You're being one crabby cracker this morning. Did you get enough sleep?

As for animal life, this is the "Crabbiest Place in the World," where 20 land and intertidal crabs range from tiny beach dwellers to the chunky robber crabs that crack coconuts with their massive claws.

"You're not crabby, are you?" "No, no, not at all. I think I'll go."
