The other night I saw a girl with pierced dimples like ....

this....

I googled for more info...and found:

"For piercings to stand out in
today's world, they need to be
really innovative. The latest wave
sweeping the counter culture scene
is pierced dimples. People are
getting their cheeks pierced either
through existing dimples or in place
of them." Modern Art Candy

But be careful not to get addicted or keep getting "the new" piercing....you may end up like this...
