to have too much of the 5th means to be a pathetic human being.

Attributes of a man should be
1 Power
2 Pace
3 Precision
4 Passion
5 Pathetic
6 Pride

A man should show as much of the 'Ps' as possible whilst not showing any of the 5th
Look at that reptile, his mrs stopped him from necking his drink like the good old days.
