burn that midnight oil

A clever way to ask your 420 friendly fuck buddy to come over late at night, do some dabs, and fuck like rabbits.

Similar to Netflix and chill.

And. . . It doesn't count if you're just smoking weed. Dabs only. kk?

Guy: Hey what r u doing?
Girl: Not much, just bored :-(
Guy: You wanna come over and burn that midnight oil?
Girl: Ummmm. . . Sure. . . why not? I haven't been high all day ;-)
