This now common saying became popular with this play. "Budge" was either not a verb, or not a commonly used verb before Shakespeare used it here to mean "stir or move." Sly represents a drunken playgoer who London's magistrates often complained about. Sly indulges in all of the corruptions associated with the theater and illicit entertainment outside the city walls, such as bear baiting and whorehouses. In this way, Shakespeare begins his play making fun of some of his audience members by including this character.
"KAT:
Asses are made to bear, and so are you.
PET:
Women are made to bear, and so are you.

This first exchange between Petruchio and Katharina shows that their wits are matched. While Petruchio believed that convincing Katharina would be easy, and Katharina believed that getting rid of Petruchio would be easy, both realize that they were wrong during this exchange. Notice that their quick back and forth lines come across like a duel of words, each turning the other's words or metaphor to use against the other.
