In Trainwreck, the unapologetic new comedy about the boozy misadventures of a disillusioned unromantic, Amy Schumer plays a promiscuous woman who embarks on countless first dates and very few second ones.

But the film’s costars say they know a thing or two about bad first dates: At the world premiere of Trainwreck in New York City on Tuesday, Schumer and her costars Vanessa Bayer and Colin Quinn chatted with PEOPLE about their very own trainwreck dates.

Schumer, for one, offered up a mea culpa. Much like her fictionalized character in the film, the actress bears the brunt of the responsibility for her nasty first dates.

“I would think that the worst date horror stories would actually be about me from other people,” she cracked. “Yeah, that’s what I would say.”

Bayer, best known for her work on Saturday Night Live, recalled a stomach-turning moment at her alma mater, the University of Pennsylvania, that ranks near the top of her least favorite dating memories.

“There was a formal I went to in college where I matched this huge guy drink for drink, and then I ended up throwing up on myself but not really knowing about it and being like, ‘We should hang out more,’ ” explained Bayer. “And he was like, ‘I’m gonna go home.’ And then I woke up a few hours late and realized that I had thrown up all over my dress. [I was like], ‘Oh, that wasn’t the coolest look.’ ”

Quinn, for one, is in the same boat as Schumer: “Unfortunately, I’m the horror in most of [my stories]. Oh my god, when I think about it [I’m] not a good person.”
