Any clue what spam flag "FB_NUMYO" is?

[thunder04]

A user recieved an e-mail that had a bunch of SPAM flags, but there was one I didn't recognize. "FB_NUMYO"

I've done some Google searches and cannot seem to turn up any information about it that I understand. Does anybody know what it means?

[root@mail2 ~]# grep FB_NUMYO /opt/zimbra/conf/spamassassin/72_active.cf 
##{ FB_NUMYO
body     FB_NUMYO               /1[0-9][\s\.]?y[\s\.]?o[\s\.]?\b/i
describe FB_NUMYO               Speaks of teenager.
##} FB_NUMYO
##{ FB_NUMYO2
body     FB_NUMYO2              /2[0-9][\s\.]?y[\s\.]?o[\s\.]?\b/i
describe FB_NUMYO2              Speaks of 20+ year old.
##} FB_NUMYO2

For example, not the 40 year old virgin.

I, uh, don't get it.

Can you explain further?

I think what it means is that that the flag is triggered if the body text contains something like "19 year old" or "21 year old". These are Perl regular expressions; in a somewhat more common (if less precise) way of expressing the strings they'd read:

1* y* o*
2* y* o*
