Sarcastic term used by a lady for a guy with a major case of "one-sided willingness" --- da dude is always ready and eager to "open his zipper" (i.e., whip out his "sausage") anytime, but
never seems all that motivated to "open his
WALLET" (i.e., "share his bacon") to help you out financially, even with just basic
stuff like groceries of household/repair materials.
