A botched attempt to fuse Farrelly-style gross out with chick flick romantic comedy. Diaz and friends are sexually liberated laddettes, oafish and obnoxious. It turns out, of course, that the three girls long to turn their back on slapperdom and find true love, the search for which takes Diaz on a cross-country road trip in pursuit of a guy whose butt she once grabbed in a nightclub. The action is padded with laboured set pieces, excruciating and pointless musical interludes and jokes about penis girth. Watching it is like being the only sober person at the hen party from hell.
