Scott Disick for the win!
In a sneak peek clip from an all-new episode of Keeping Up With the Kardashians, the 33-year-old reality star hilariously shades his ex-girlfriend, Kourtney Kardashian, while playing Cards Against Humanity, the "party game for horrible people," during a family ski trip.

If you're not familiar with the game, it's simple: Each player draws ten white cards. Then, one player chooses a black card that requires an answer. The rest of the players reply with a white card to fill in the blanks or answer the question. The funniest white card wins that round, and in this case, Lord Disick was the clear victor!
In the clip, Kourtney, Scott, Khloe Kardashian, Kendall and Kylie Jenner, and Tyga (who was still dating Kylie at the time) and their pal, Todd Kraines, gather together around a table to play. Kourtney draws a black card that reads, "Why am I sticky?"
Kourtney, 37, begins reading the white cards that were played -- "a fleshlight, your weird brother, still being a virgin" -- but smirks and nervously plays with her hair when she reads "Justin Bieber."

Kourtney first sparked romance rumors with the 22-year-old pop star last October when the two started spending a lot of time together. The "Sorry" singer partied with Kourtney at The Nice Guy, a celebrity hot spot in West Hollywood, California, later attending Universal Studios Hollywood's "Halloween Horror Nights" together. Two months later, Kourtney attended one of Justin's impromptu performances at the same venue.
Kourtney and Justin, who are longtime family friends and neighbors, addressed the rumors during two separate interviews. While chatting with Ellen DeGeneres in December, Kourtney played coy and insisted they were "just friends."
During his appearance on The Bert Show, a nationally syndicated radio program, Justin joked that he was "being used, man." He quickly shut down the rumors, however, saying, "Na, we'll leave it at that."
