Blarney

The difference between blarney and baloney via Fulton Sheen (paraphrased):

When meeting for the first time a woman of 40ish:

Baloney: You don't look a day over 18!

Blarney: Tell me your age so I know that age when women are most beautiful!

Another way he puts it:

Blarney is flattery so thin you love it. Baloney is flattery so thick you hate it.

Oremus pro invicem!
