In the pilot episode of Friends Monica meets this handsome guy and they have sex in her flat. Next day in the morning, she kisses him off and then she has this conversation with Rachel:

Monica: So how're you doing today? You-you sleep ok? You talked to Barry? I can't stop smiling.

Rachel: I can see that. You look like you slept with a hanger in your mouth.

Monica: I know, he, he's just so... You remember you and Tony DeMarco?

Rachel Oh, yeah.

Monica: Well, it's like that. With feelings

Rachel: Oh wow. Are you in trouble.

Monica: Big time!

I have no idea what hanger means here and how it is related to her smiling.

She means that Monica's smile was so wide, and given the fact that she couldn't control smiling, was metaphorically compared to having a hanger inside her mouth, overnight, which would force her jaw open, to make it look like she was smiling, as shown below.

Since she couldn't stop smiling due to her night with that guy, which obviously is the reason for her super-wide smile, Rachael used the phrase 'you slept with a hanger in your mouth' to try and relate to why she couldn't stop smiling, to having Monica's jaw forced to take the shape of a smile by retaining a hanger in her mouth all night.

  • To make it more clear, a hanger is this.

  • I guess it means smiling with a wide mouth. This kind of slang exists in Persian too. Oct 22, 2018 at 10:27

A hanger (used for hanging clothes on) in your mouth make your mouth wide open, not vertically but horizontally.
