Wanna hit up a coffee 
joint with me after this?!
Das ist alt!!
¿No quieres ir conmigo
a tomar una tacita de café?
¿Te vienes conmigo a tomar un cafelito?
Ça te dit de prendre un café glacé
avec moi ?
Dopo le lezioni ti va di andare
a prendere un caffè insieme?!
Que tal tomar um cafezinho
comigo depois disso?!
Как насчёт выпить кофейку
после уроков?
