Flimpty

When someone does something that could be considered a "low blow" to others.

"What you did to her was very flimpty !"
"As flimpty as it is, I needed to win the match."

flimptie

the hero in a children's fairy story, who saves
Flimptieland from the evil Zurtledurks with the aid of the good fairy Tumshee, the love of his life.

A Flimptie is a fearless thing
He’ll dragons slay and treasures bring.
He’s fleet of foot and soft of heart
And from him Tumshees never part
Is he real, or just a dream?
He’s flesh and bone so it would seem.
Or does he dwell in a secret place
Where no one ever sees his face?
