The verb χασαλβάσω (future of χασαλβάζω) is a hapax legomenon in Aristophanes and rare in the surviving corpus. It denotes a specific, coarse action of pouring or splashing, likely onomatopoeic in origin, here used to describe the pouring of wine over the heads of the generals. The form χοᾶ (from χέω) is an imperative aorist, but the syntax presents a crux: the construction 'χοᾶ [instrumental/locative of liquid] χασαλβάσω' implies a sequential or manner-based relationship that is syntactically compressed. The phrase 'τοὺς ἐν Πύλῳ στρατηγούς' refers to the four Athenian generals (Demosthenes, Nicostratus, Thrasylaus, and Epicles) who were trapped in Pylos during the Peloponnesian War, a specific historical reference that Aristophanes mocks by suggesting they be drenched with wine rather than honored, playing on the contrast between their military stalemate and the festive, drunken atmosphere of the symposium.
