BAT

Kewl kids use BAT as shorthand for "bada** trick." You're most likely to receive this abbreviation in text or chat messages, alongside a video of the sick trick it references.

For example, your friend Kyle might send you a message that reads "Check out this BAT," accompanied by a video of a skateboarder pulling off a lengthy darkslide. Most likely, the video Kyle sent you will feature a rad skateboard trick and will not feature a bat. (But who knows? Maybe it'll have both.)
