Flair in Bridge?

Today at Tanglin, there was a pair who went to 6S when everyone else stopped in game. 6S and 6NT were both cold, because 3 finesses were onside, but otherwise, the slams would not make. My partner asked one of the pair why he went to 6. He said it was due to 'flair'.

I then told him what I thought 'flair' was.

Flair is not bidding over your opponent's 4S preempt, even though you have a 3-6-4 hand, have more than a maximum opening hand, know that your partner has points, are void in spades, and have yet to show additional length in your 1st bid suit. This ensures that partner will be the one playing the grand slam he induces his partner to bid by his bid. (This is very important - stress is not good for you =P.)

Flair is bidding a new suit at the 5 level, knowing that partner will spawn honours in that suit for you. (She always does, yah?) This flair is accentuated by the fact that you have only 8 points, none of which are in that suit.

Flair is dropping the offside singleton King of trumps to make the cold grand.

And, of course, flair is the ability to provide partner with the AQJx of the new suit he decides to bid at the 5 level.

Hand can be viewed here (Under Contract: 7 by south). There was no defiance involved. If I bid like that, I would also expect partner holding AQJx in my bid suit to raise me to the grand.
