For those who have regrettably not been keeping up with the many Kardashians, allow us to offer a crash course.

Kourtney, the eldest sister, is currently on an all-out Instagram brigade to make her ex-husband Scott Disick, who recently photographed hooking up with 19-year-old Bella Thorne in Miami, very jealous. It's extremely petty of her, no doubt, but we are unabashed lover of a good Instagram revenge plot.

In her latest strike, Kourtney just shared an image of her lounging in a poolside in a tan bikini, with her assets on a bountiful and eye-catching display.

The motto stitched onto her hat was even better: "Fucked Up Friends Club." Sure, her romantic life is a disaster, but Kourtney can take the heat.

This Kardashian has definitively proven that you can win the Instagram battle and the Instagram war at the same time. Solider on, Kourtney!
