1. a motorcycle (usually sportbike) that is travelling at an unusually slow speed;
often used to insult a fellow biker
2. the bike portion of the Batmobile from the movie "Dark Night"; which we see our beloved Batman cape-flapping through Gotham at break-neck speeds of up to 30mph
"Against your Batmobike? I'd better take off my shoes, I run faster bare-footed..."
"I checked my mirrors for him, but all I could see was his cape flapping."
"When are you gonna sell that Batmobike and get a Huffy?"
