Most people who give their spouse a nickname typically choose something sweet and adorable — butMeghan Trainorhad other ideas!

While appearing on an episode ofA Little Late with Lilly Singhon Wednesday night, Trainor, 25, talked about her husbandDaryl Sabaraand how much theSpy Kidsstar, 27, means to her.

“I am his number one fan,” Trainor gushed to Singh, 31. “He’s the most supportive human being ever and the nicest guy in the world. Like, you won’t believe how nice he is.”

The singer then revealed that despite Sabara’s kindness, she and her brothers had given him the nickname of “Serial Killer.”

“If you date or marry me — which he did — you gotta kinda marry my brothers, as well, and we call him Serial Killer,” she explained. “I’ll be like, ‘Hey sugar’ or some weird stuff, but when we’re talking about him, it’s ‘Serial Killer’ because he looks crazy in a lot of pictures.”

It wasn’t just Sabara’s physical appearance in photos that prompted Trainor and her brothers to call him the nickname.

“And he never has sauce on anything, not even salad! Just dry!” the singer added. “I begged him, ‘Just try this sauce, is it the wrong sauce?’ and he’s like, ‘I like the grass taste’ and I was like, ‘You’re crazy!'”

“Meanwhile, I’m like four dips, each one,” she joked.

“I am aggressive,” Trainor told PEOPLE in May. “I am very like, ‘I want it, I want it now!’ Whenwe went on our honeymoon, I was so inspired, I was like, ‘We should just do it now!’ And then I was like, ‘Wait a second, I have to go back and work a lot.’ So,we didn’t do it. I am not ‘preggos.’I just cannot wait though.”

Indeed, Sabara can’t wait to be a dad. “I feel like we’ve already been married since we’ve been together, but I guess it’s just that special bond,” he told PEOPLE in January. “We just want kids. I’m excited to be her husband so I can be a dad and we can have kids together.”

Trainor also joked to PEOPLE in May that she and Sabara were “gross” about how “obsessed with each other, from the beginning” they were in their relationship, even saying “I love you” as early as “day six.” But it works for them, as the affection is mutual.

“By month one, we were like, ‘We’re getting married and having two kids!’ We kind of locked it down. I’m kind of obsessive like that,” she said. “I guess [marriage] doesn’t feel different except for the fact that everyone on the outsideknows how we feel on the inside.”

“That is how we say it, and it may sound a little weird and gross, but now you guys can understand howobsessed we are with each other,” Trainor quipped.
