The replacing of the last segment of a word with the letter z or -iz, -az, -ez or some similar form. Add whatever form fits the word or sounds the best. Best used typically in context, so as to avoid confusion when "Triz" or "Traz" could mean multiple things; tree, trash, trench, treat, Trish, triad or triarch.
Guy:"Dude, take out the triz..."
Guy:"The Z rule...*sigh* take out the trash..."
