To steal in a sophisticated and cunning manner. To convince (much like a confidence man) someone to part with a valuable and, if the finneagler is particularly skillful, to do so believing that it is actually what the finneagled want. Furthermore, to finneagle would be to convince someone that by handing over their valuables, it is helping the finneagler out of a jam or trouble.

To have been conned out of something. To have been convinced by a finneagler to party with something of value. To have been the target of a con man's finneagle.
Man, it happened again. She saunters over, pouts her lips, squeezes her tits together, leans close and whispers in my ears and, bang!, my cash for the night is gone. I've been finneagles again!
