Come, Kate, and wash, and welcome heartily.
You whoreson villain! will you let it fall?
Strikes him

you whoreson villain: meaning you son of a slut. This is a little bit worse than modern day cussing as people generally do not get other family members involved. This could be said because petruchio wants to offend people, and he wants to be known as a bad person and wants to become the shrew between him a katerina.

KATHARINA

Patience, I pray you; ’twas a fault unwilling.

PETRUCHIO

A whoreson beetle-headed, flap-ear’d knave!
Come, Kate, sit down; I know you have a stomach.
Will you give thanks, sweet Kate; or else shall I?
What’s this? mutton?

First Servant

Ay.

PETRUCHIO

Who brought it?

PETER

I.

PETRUCHIO

‘Tis burnt; and so is all the meat.
What dogs are these! Where is the rascal cook?
How durst you, villains, bring it from the dresser,
And serve it thus to me that love it not?
Theretake it to you, trenchers, cups, and all;
Throws the meat, & c. about the stage

You heedless joltheads and unmanner’d slaves!
What, do you grumble? I’ll be with you straight.

KATHARINA

I pray you, husband, be not so disquiet:
The meat was well, if you were so contented.
