Quote:
Do not torpedo single friends
I believe this refers to when an attached friend sabotages the attempt of a single friend in seducing a young lady. It is common for attached friends to try and get "technical" pulls, in other words seducing a girl without any intention of doing anything. This can be terribly annoying, as people have more confidence when attached - they don't really care about the outcome, they can have that debonair attitude that women find attractive. It does however mean that the female target has decided in her mind who she fancies, and thereby scuppering the chances of the slightly stuttering single guy.
