[Lenehan, alone in pub here, reflects on Corley's most recent adventure]
When he had eaten all the peas he sipped his ginger beer and sat for
some time thinking of Corley's adventure. In his imagination he beheld
the pair of lovers walking along some dark road; he heard Corley's voice
in deep energetic gallantries, and saw again the leer of the young
woman's mouth. This vision made him feel keenly his own poverty of purse
James Joyce, Dubliners (Two Gallants)
"saw again the leer of the young woman's mouth"
The meaning I've found for "leer"
a sly, sinister, or immodest glance: a knowing or wanton look
doesn't seem to cover Joyce's usage: a mouth cannot throw a glance/look:-)
Does the OED offer a more inclusive definition?
