Blase Boast

The Blasé Boast is Badass Boast being played as if it were ordinary business.

It may look like someone acting dismissive of their deeds, but the boaster is actually very proud of them. They are just being dismissive to mess with someone's head, or to seem more Badass.

If the "boaster" is honestly dismissive of what they did they're just saying But for Me It Was Tuesday and thus not a boaster. If they're ashamed, they won't bring it up outside of Your Approval Fills Me with Shame or Never Live It Down.

Compare Think Nothing of It.

Literature

While you're waiting for your turn, I suggest you give careful thought to which four of you deserve to die for what you've done--because I'm going to ask you that, and I'll know if you're lying. That's the fairest way I know to see that justice is done--though I'm sure His Majesty is right that more than four of you probably deserve to hang.""
