Feels that that AUS guy is boasting to everyone that :
- He is irresistable - 'dunno what that women sees in me leh'.
- He is far superior than the woman's husband, as the husband can't do anything about it.
- He's a living example that there's such a thing as free lunch.
Although we should not judge, but sometimes there are people who do crash with our values and get on our nerves.
