to make someone believe something that’s completely fake and then laugh at them for it

I finnesed my dad by telling him the TV was broken, but it was just me watching YouTube.

She finnesed her friend by saying the pizza was gone, but it was just under the couch.

He finnesed his sister by saying the dog ran away, but it was just hiding in the closet.
