AMERICAN teen movies have travelled this puerile road before, and will do so again because there is always a randy and ready new audience looking to pop its cherry too.

Move over Animal House, Porky’s and the endless slices of American Pie, here comes more of the same smut from Sean Anders, a writer-director with a deficit of originality but an overload of enthusiasm and enough stereotype send-ups, awkward collisions and bawdy gags to press teenage buttons.

In Eighties’ John Hughes tradition, Anders hurls a reluctant virgin into the epicentre of the testosterone storm, in this case 18-year-old Ian Lafferty (Josh Zuckerman), a Chicago nerd desperate to get laid before college freshman days dawn.

Darn it, his younger brother has had more success, his bullying, homophobic elder brother Rex (James Marsden) is always on his case, and Felicia (Amanda Crew), his long-time best friend, will never be more than that, or will she?

God bless the internet, as he “connects” with the voluptuous Ms Tasty (Katrina Bowden), and off he goes with laidback, libidinous smarmy pal Lance (Clark Duke) and Felicia on a 500-mile road trip to Knoxville to have his first taste of fantasy totty Tasty.

Commandeering Rex’s prized vintage red Pontiac without approval, they should be there in eight hours, but gun-toting cops, car trouble, brotherly bother, a jealous husband and a detour into the Amish farm community turn their jaunt into a three-day tour of teen hell.

Anders and his young cast tick all the obvious boxes, working the indefatigable formula to the max, always with one eye to the tasteless. While as many jokes crash as fly, Seth Green’s sarcastic cameo as an Amish mechanic is a particularly guilty pleasure amid the Midwestern mayhem.
