[Intro: Charli xcx]
Hey, Billie, you there?
Uh-uh

[Verse 1: Charli xcx]
You wanna guess the colour of my underwear
You wanna know what I got goin` on down there
Is it pretty in pink or all see-through?
Is it showin` off my brand-new lower-back tattoo?
You wanna put `em in your mouth, pull `em all down south
You wanna turn this shit out, that`s what I`m talkin` about
Pu-pu-pu-put `em in your mouth, pull `em all down south
You wanna turn this shit out, that`s what l`m talkin` about (Yeah)

[Chorus: Charli xcx]
Try it, bite it, lick it, spit it
Pull it to the side and get all up in it
Wear `em, post `em, might remix it
Send `em to The Dare, yeah, I think he`s with it
Try it, bite it, lick it, spit it
Pull it to the side and get all up in it
Wear `em, post `em, might remix it
Eat it up for lunch, yeah, it`s so delicious
(Work it out)

[Verse 2: Billie Eilish]
Don`t have to guess the color of your underwear
Already know what you`ve got goin` on down there
It`s that lacy black pair with the little bows
The ones I picked out for you in Tokyo
I saw them when you sat down, they were peekin` out
I`m gonna tell you right now, they`re all I`m thinkin` about

[Chorus: Billie Eilish]
I wanna try it, bite it, lick it, spit it
Pull it to the side and get all up in it
Kiss it, ride it, can I fit it?
Charli likes boys, but she knows I`d hit it
(Knows I`d hit it)
Charli, call me if you`re with it

[Bridge: Charli xcx, Billie Eilish, Charli xcx & Billie Eilish]
Yeah, guess, guess, guess, guess, guess, guess, guess, guess
Guess, guess, guess, guess, guess, guess, guess, guess
Guess, guess, guess, guess, guess, guess, guess, guess
Guess, guess, guess, guess, guess, guess, guess, guess

[Outro: Charli xcx, Billie Eilish, Charli xcx & Billie Eilish]
You wanna guess what me and Billie have been textin` about? (We`ve been disrespectful)
Still tryin` to guess the password to my Google Drive (Are you obsessed with me?)
You wanna guess the address of the party we`re at (You know you`re not invited)
You wanna guess if we`re serious about this song
