Scott Disick, everyone’s least favorite Kardashian companion, is doing what he does best… being a D-Bag.

The boyfriend to Kourtney Kardashian was spotted last night cozying up to a “hot blonde” and acting like an a**hole to his waitress!

While Kourtney was taking care of their two children Mason and Penelope, Scott was having a wild night out with his buddies at the Mohegan Sun Casino in Connecticut (random).

Apparently Scott was seen with “his arm slung cozily around a hot blonde with her hair in a topknot.”

Not only was Disick canoodling with a random girl, he was also being “incredibly mean” to his waitress.

“He literally ripped the bottle out of my hands when I came to the table, and later, he and his friends were just dumping drinks on me. I’m glad to be done with their table for sure,” the waitress was overheard saying.

Wow a 29-year-old man dumping drinks on a waitress… someone please slap the paste out of him!

“He stayed until 1 a.m., but I’m sure the after-party in his suite was epic,” an eye witness reveals. “It seemed so obvious his relationship with Kourtney is for show.”

“He’s using her name to be able to headline events like this and get free booze and chicks for himself and his friends. Meanwhile, she’s at home with two kids. It’s sad.”

Yup he’s definitely in the running for Dad of the Year, right behind Michael Lohan!
