21 and Over Dares You to Get Offended   It's hard to know what
to laugh at anymore -- the only guideline, maybe, is that we'll
know it when we see it. And Jon Lucas and Scott Moore's guy-
humor extravaganza 21 & Over isn't quite it. 21 & Over, in which
three college guys set out for a night of drinking and, they
hope, debauchery, is filled with crude gags that almost tip into
the red on the bad-taste-ometer: One of its characters, in a
drunken stupor, eats a tampon -- unused, thank God, as this
isn't a Catherine Breillat movie. The trio crash a sorority
house filled with tough, angry Latinas -- stereotype alert! One
of the guys tosses his cookies while riding a mechanical bull;
his puke spins into the air in slow motion, a visual symphony of
pearlescent beige droplets. There's even an uptight Asian girl
who plays field hockey -- stereotype alert number two! You can
almost see the minds of the filmmakers working: Someone out
there has just got to take umbrage at 21 & Over -- please.
