pound
n.— «Well, now the latest thing is called…knuckles, and this one looks like it’s going to be around for a while. I’ve heard a few people refer to it as a “pound” but whatever the case is, it’s gotten totally out of hand. I walk into work and colleagues greet each other with knuckles. “How was your weekend man?” (Knuckles extended as the question comes out of his mouth).» —“A changing of the guard in the handshake department” by Doug Hastings Burlington Union (Vermont) Oct. 26, 2006.
