The movie is a faux-documentary, illustrating mankind's need (and womankind's less obvious but equally present need) to get down, as well as the steps necessary to achieve this. Using a combination of staged party footage, hilarious graphics and laboratory demonstrations with inebriated mice, the film walks you through 16 chapters about such topics as "How to Get Past the Velvet Rope," "Bartender Tipping Etiquette to Ensure Free Drinks" and "The Secret Afterparty."
Being a frequent nightclub wallflower and typically the last sober person at the party, I can attest that many of the film's earlier observations are spot-on. There does seem to be a correlation between the exclusiveness of the party and the number of "hot dog" folds on the back of the bouncer's neck. And the location of a drunken house party does appear to be marked by guys urinating outdoors. The dry narration and serious use of terms like "horndog" and "pussy power" add to the hilarity.
But around the film's midpoint, the narration becomes less frequent and the authentic observational humor gives way to crude sketch comedy. We're given much more contrived situations such as the "Fauxmosexual," in which a man pretends to be gay at a gay club so that the straight woman dancing there will become determined to convert him. He thinks he's victorious until a gay man gets into the cab with them, revealing they're about to take part in a threesome. Yeah, we've all been there.
Occasionally, the film also suffers curious tonal shifts. It takes the stern and responsible stance that party-goers shouldn't drink and drive ... right after describing in elaborate detail how you can salvage dampened cocaine with incremental use of a microwave.
The Boys & Girls Guide seems geared toward college kids, and drunken antics, ample drug humor and frequent toplessness is probably more than enough to please that demographic. It's just a shame that a film with the makings of brilliant satire should end with an afterparty that wouldn't be out of place in an American Pie movie.
