Green’s Dictionary of Slang

wussify v.

to render weak.

Dr. Verne’s Northern White Trash Etiquette, Verne Edstrom, iUniverse (Lincoln, NE) 1 Nov. 22: Let him know that you care too much to see him go wussified, that if he don’t quit that damn registered nursing, God’ll send him to the dainty part of Hell, where they only serve Coors Light and the big screens all show figure skating. [Ibid.] 57: I got this problem. They’re trying to wussify me.
