a girl turns up to a male geek's room in the night
wearing a jacket and no top. If he notices you're topless
or mentions it, he's passed. If he doesn't get that your boobs
are out, he has failed
the geek test. Bra is optional depending on how much of a geek this guy could be.
Guys can also
do this test, obviously without a bra, but it works much better when
women do it.
