The Word -Lambaste

"Giving up so quickly?"
"You've already proven that I can't beat you, so go ahead and lambaste me already." He glanced back, not wanting to but unable to resist. Why wasn't he already being forced down to all fours again?
Yorvet smiled. "Well, at least you recognize that you can't beat me." He shrugged a shoulder. "Return to camp. Get there before the fires are doused and you can stay human." Yorvet raised his hands and vanished in the blink of an eye.

Added Info - The origins of "lambaste" are somewhat uncertain, but the word was most likely formed by combining the verbs "lam" and "baste," both of which mean "to beat severely." (Incidentally, "lambaste" can also be spelled "lambast," despite the modern spelling of the verb "baste.") Some other synonyms of "lambaste" include "pummel," "thrash," and "pound." "Pummel" suggests beating with one's fists ("the bully pummeled the smaller child until teachers intervened"). "Pound" also suggests heavy blows, though perhaps not quite so much as "pummel," and may imply a continuous rain of blows ("she pounded on the door"). "Thrash" means to strike repeatedly and thoroughly as if with a whip ("the boxer thrashed his opponent").
