Tussle.
A struggle, a skirmish. A corruption of tousle (German, zausen, to pull); hence a dog is named Towser (pull em down). In the Winters Tale (iv. 4.), Autolycus says to the Shepherd, I toze from thee thy business (pump or draw out of thee). In Measure for Measure, Escalus says to the Duke, Well touze thee joint by joint (v. 1.).
