Awaiting an outcome, or termination, of something with almost unbearable anticipation (as in clenching one's fists tightly to get through the agonizing final days or moments of waiting for something to happen or be over with)
Brooke's mom was told she couldn't have a drink for 30 days before the wedding, and she knew she would have to white-knuckle it!

 Get the Knuckle Puckmug.
Get the Knuckle Puckmug. A sexual act performed by a male/female couple and a third which can be male or female. The couple prepare for sex in the doggie styleposition. The third party then cups the male's balls in the palm of their hand and extends their middle finger out and along and against the bottom of the male's cock. The male then proceeds to enter the vagina filling her with both his cock and finger of their partner at the same time. Thus giving her a satisfying knob and knuckle.
Joey and Sasha had a threeway with their firend Lou. She was most satisfied when Lou and Joey gave her a Knob and Knuckle.

 Get the CORN KNUCKLINGmug.
Get the CORN KNUCKLINGmug. Knuckles the echidna is one tough dude. Always protecting the Master Emerald from anything/anyone that could take it. He's a loner, he's gullible, and very shy around certain girls. He's the only reason that you should be playing any Sonic The Hedegehog games. He's also got good manners, but when he's around Rouge the bat, he changes all that (even though Knuckles secretly loves Rouge) because he knows that she's after the Master Emerald.
Knuckles The Echidna and Rouge The Bat do belong together, they're just meant together know what I mean? Anyway, Knuckles really is the best out of all the Sonic characters. I LUV KNUCKLES!
