meaning of 'jump up and bite for'

Ever since you got that Ivy League scholarship, you’ve been hooked on their teat. You think you’re one of them because you go on their ski vacations and their yachts. The Man snaps his fingers, you jump up and bite for him.

The speaker is angry that his best friend gave the speaker the back. Both hispanic and 'them' means white people.

And I can't understand that 'The Man snaps his fingers, you jump up and bite for him'. In this dialogue, 'The man' means 'the owner of a dog' and 'you' means 'a dog'? I guess it means 'You are like a dog to them'.

But I'm not sure. Help me understand this dialogue perfectly!

(My native language is not English. Please be kind to me. :-))

Solution 1:

You misunderstand the parsing of the sentence.

you jump up and bite for him

'You' is the subject, 'jump up and bite' is the compound verb, 'for' is the preposition and 'him' is the (indirect) object. In other words:

What do you do? You "jump up and bite". Who do you do it for? You do it for him (the Man), meaning because he wants you to.

"The Man" does not usually refer to the owner of a dog, but to "the boss" or "the ruling class". However the use of "jump up and bite" is clearly indicating your similarity to the behaviour of a dog that does whatever its owner wants.
