Unnamed Town "Squirt"

In one of his memories in The Sound and the Fury Quentin berates Caddy for "letting it be some darn town squirt" who kissed her (134). A "town squirt" is presumably a young man from a lower class than the Compsons - that same implication is there in Quentin's reference to "the town squirts that Father was always teasing her about" (174) - but it's not clear if Quentin is thinking of any one particular boy here, or remembering one particular event.
