The headword is the perfect middle participle, in the feminine dative singular, of the verb diaspleko/w; cf. also spleko/w in Aristophanes, Lysistrata 152 (pi 1722). It can also be written pl- or spekl-; cf. Pollux 5.93. For the violent vulgarity of the term (reflected in translation here) see J. Henderson, The Maculate Muse (New Haven 1975) 154 #214.
[1] Aristophanes, Plutus [Wealth] 1082-1083 (web address 1), with comment from the scholia there; copied to pi 1723. A young man urged to resume a relationship (cf. line 1081) with an old woman is finding an excuse to discard her.
[2] The verb diale/gesqai, literally meaning "converse with" can also have a sexual meaning; likewise other verbs such as su/neimi, suggi/gnomai etc. Cf. Hyperides fr.171 Jensen and Plutarch, Solon 20.3.
[3] If this text is to be retained, 'years' comes unexpectedly (para\ prosdoki/an). The audience may well have expected "thirteen thousand men" or the like, and some scholars would emend e)tw=n to produce this: au)tw=n or te tw=nde; see e.g. O'Neill's translation at web address 1). Arguably mockery of the woman's age is more likely (but in that case [DW] adopt Kuster's a)po/ for u(po/). The poet is probably playing with a metaphorical sense of the word, as "ravaged" or "ruined". Similar use of a sexual-related word first by Suetonius, Caesar 51 aurum...effutuisti "you did squander away the riches".
[4] cf. the scholion Ravennas on the verses, which reads to\ sple/kwma instead of to\ ple/kein and adds: to\n h)=xon de\ le/gei to\n gino/menon e)n th=| sunousi/a|; "it means the sound made in the act". The Suda seems to imply a confusion with ple/kw, probably due to the meaning of "twine".
