I mean the person who only has the gut on bullying small guys, but when he faces big guy, he will surrender and give in like a puppet.
'bully' was suggested by someone before, but it obvious is not precise enough.
Any suggestion? thanks.
edit: If there isn't a single word to say such a person, what are some idiomatic terms or words for describing?
I still feel that 'bully' isn't precise enough in describing a person like that, because a bully could sometimes bully someone bigger than him, it's possible and personally I saw this kind of bully before. Besides, 'bully' doesn't carry the connotation of "when he faces big guy, he will surrender and give in like a puppet."

"Bully" does contain the idea of someone who ONLY picks on smaller persons and who won't pick on someone his or her own size, thereby carrying with it the sense you are seeking.
