(have) got it going on

1. To be particularly attractive, especially romantically or sexually. I've gotta say, Keith's new girlfriend has definitely got it going on. You're looking good today—you got it going on! That girl at the bar has got it going on! There's no way she's going to talk to a dork like you.

2. To be very successful, impressive, or exceptional. With a top job at the bank, an amazing wife, and a vacation home in the south of France, Jennifer's got it going on these days. Three hit movies in a row? That actor's really got it going on. Our company struggled for a long time, but we've got it going on now with this new product.
