3. Because he made these two phrases famous, a 3rd synonym became used within baseball, and now pop culture, to pull a "Mark Grace", also meaning to break a slump by boning an ugly or fat chick.

When you havent gotten laid in forever, and you wind up taking home the first piece of ass you can. (Can be on purpose or by accident)
