VOID

To urinate. Just as we can void a check and empty it of value, so can we void our bladder and empty it of urine. According to Merriam Webster’s Collegiate Dictionary, the intransitive form of the verb "void" means "to eliminate solid or liquid waste from the body." We do not agree with this definition. "Void" in this sense is only applied to "liquid waste" (urine), never to "solid waste’ (feces).
