She got a 9 on her seduction roll.

The story:

I **sumed the line was referring to a tabletop
roleplaying game, and that the seduction check
required a D10.

I told my DnD group this, they listened to it on
the same crappy speakers and agreed with me. We
all went several years thinking AC/DC were a bunch
of Dungeons and Dragons playing nerds like us.

Obviously when I found out otherwise it was very
disappointing.
