Remembored

The word remembored, repeated five times in the first ten pages of II.4 (once in the initial collective remembrance of the Four Old Men, and once for each of their individual remembrances), seems to be a hint from Joyce that the reminiscences are intentionally boring.

I'm taking the word boring here to be a reference to the sexual act, since they all seem to be dirty old men who like watching them do it, and it's making them remember their own youth. There are repetitions of the interjection (up) every time they get to the good bits too, which is a sexual joke in Ulysses, and appears to be a reference to getting an erection. So for me rememboring is the old men remembering their past sex lives.
