"Rollo de una noche" = Roll of one night*

One night stand. It is said that when people get together with a sexual intention they are going to "enrollarse" (roll themselves), which happens to convey a very graphic image. However, "enrollarse" can also mean 1) fam (hablar mucho tiempo) to go on and on: "¡no te enrolles!" --> stop it / shut it 2) argot (actuar, responder) "¡enróllate!" --> be a sport! "tu amiga se enrolla fatal" --> your friend gets on very badly with people

"No me van nada los rollos de una noche" "Es una persona de rollos de una noche, sin compromisos ni complicaciones"
