put a/the plug in the jug(redirected from put the plug in the just)
put a/the plug in the jug
To become permanently sober; to give up intoxicants, especially alcohol. (Alludes to plugging up a jug of an alcoholic beverage.) I've always loved my dad, but he's become a much friendlier and sympathetic person since finally putting the plug in the jug. It took me waking up in a ditch and covered in vomit to realize that I needed to put a plug in the jug for good.
