Dewclaws Up 

Show of approval, Thumbs up (as the dewclaws of a canine are essentially their thumbs)

Usage:
"I gotta squat for a jiffy wiz in The Gran Manzana and I've been head sparkin’ ‘bout pounding that Coney fillet in a twee fire-in-the-hole.
Dewclaws up. Ya wanna draft my flivver?
Bang the pipes by 5:00 or hold peace.”

Translation:
"I’ve got a layover in New York City and was thinking about getting a hotdog in a quaint restaurant.
I’m enthusiastic. Do you want to come along?
Call me by 5:00 or it will be too late."

Dude: Scope those curvacious maidens. I’ll pounce the coal top with the bouncing betties. What’s your ruling on the blonde?
Wingman: The dewclaws are up.
