This one won't really fit, but I sure wish it would...
I come out of my stop, around lunch time, and 3 guys are huddled around my Empulse, holding forth on electric bikes. Two are in their 30's and one kid around 20 or so. I hear one guy say, "Yeah, I saw one at a drag race and it was really fast!"
I walk up, gray hair, bald head, ATGATT, and join in the conversation: "Yep. 60 mph in just 1 second... that's what the Kill-A-Watt will do."
They turn, accepting my input with the ease of workmen not in a hurry to return to drywall, and I hear the word, "Bad-ass." Thinking they're talking about the total sweetness of my ride, I say, "Yeah, they sure did a great job designing it!"
"No. YOU, dude! You're one bad-ass codger!"
So, maybe "BAC" on my plate and only the readers here will know the meaning.
