When you and your friends are playing the card game Hearts, and one player insistently Wallflowers, unless to stop a Power Run. In this case, they unflower themselves, and stick out their large, often bumpy nose.
Nad was Power Running like a champ, when all of the sudden Jiffy stuck out his nose and stopped the run.
"Fuckin A," said Nad. "I didn't see you Walljewing there, Jiffy! Wtf!"
"Hehehehe," chuckled Jiffy as he rubbed his nose.
