It's good

Dude has very high standards. If he says it's good, it's actually very good by normal standards. But he just won't say 'very good' coz 'very good' has another meaning to him. Now that's 'very' confusing.

Usage:

Wife: Look dude, this dress looks very good.
Dude: It's okay.
Wife: What?
Dude: It's good.
