Lala, James and James' friend, Logan, were at lunch when James brought up that he was going to ask his girlfriend, Raquel, to move in with him. James had already thrown back a few shots by the time he shared the news with his friends, and therefore misread their reaction.
"Do you have a problem with her?" James asked Logan.
In an effort to smooth over the situation, Lala told James a funny story about the last time they all hung out. "We ate all her pasta, and she didn't give us permission," she said laughing.
James' face dropped. "You're a bitch," he said. "James, what is triggering you?" a confused Lala asked.
"My feelings are that you don't like my girlfriend," he said. "You think you can be mean? You wanna bully a little girl with her pasta? Poor Raquel? Who is more beautiful of a woman than you'll ever be?"
Lala quickly went from confused to pissed off. "Raquel offered me her pasta," she said.
"Don't f-ck with my bitch because I will f-ck with your fat c-ck man," James shouted. "He's gonna get bored of you and he's gonna be onto the next young, pretty blonde, if you want the truth."
"You f-ck the fat man because he pays for your rent!" James shouted.
Lala finally snapped: "You know what? You can't say whatever the f-ck you want. Learn your f-cking place, motherf-cker, or else you're gonna learn real goddamn quick when you look next to you and I'm not there anymore, and you're gonna be real f-cking upset. So know how the f-ck to talk to somebody when they're your friend. I'm out."
