The headword verb pasxhtia/w is rather coyly translated in LSJ as 'feel lust, esp. of unnatural lust'. More precisely it refers to playing the passive role in sexual intercourse (what Jeffrey Henderson in The Maculate Muse calls pathic homosexuality).
The present headword -- its present active indicative or subjunctive, third person singular -- is rare and must be quoted from somewhere. For an instance of it (which perhaps lies behind these lexicographic entries) see Athenaeus, Deipnosophists 5.187C (5.12 Kaibel): it disapprovingly summarises Alcibiades' (alpha 1280) appearance in Plato's Symposium, evidently with particular reference to Alc.'s relationship with Socrates (sigma 829), by complaining that Alc. 'says that he longs for passivity' (le/gonta o(/ti pasxhtia|=).
