A "thing," as in, "Are you doing that leadership conference jag this weekend?"

"Karen, do you like the new My Chemical Romance CD?"
"Nah, emo music isn't really my jag."

jag 

Just-A-Guy or Just-A-Girl. He's better than a SLUG (Semi Lingering Under-Average Guy), but he's really just a guy. It's NEVA his world - not now, not neva.

What a Jag!

jag 

A term used by retards on their social media the day after they partied. They want everyone to know that something went wrong (they messed up / got caught/ didn't have fun). Then they do the same exact thing next weekend, and also call it a jag.

If only last night wasn't such a jag.
Chloe's party was such a jag!
