He didn’t like to think of himself as the sort of person who giggled or sniggered, but he had to admit that he had been giggling and sniggering almost continuously for well over half an hour now.

Our reading
An editorial interpretation.
This captures the sheepish realization of catching yourself in an uncharacteristic fit of laughter, someone who doesn't see himself as a giggler suddenly noticing he's been helplessly giggling and sniggering for half an hour straight. It's a gently comic moment of self-aware surprise at your own silliness.
