Morphology
The meaning 'to drink all the liquid in a cup' is directly derivable from combining 'drain' (to cause liquid to flow out / to empty) with 'cup' (a drinking container); a B1 learner who knows both words will understand this as emptying the cup. There is minor ambiguity about the method (drinking vs pouring), but the core idea of emptying the container to the last drop is transparent and follows normal compositional logic.
Etymology
Drain the cup comes from the simple image of tipping a cup so the last drops run out and you drain it. That's why it means 'to drink to the last drop'.
