noun / verb
snigger
SNIG-er/ˈsnɪɡər/
A quiet, disrespectful or silly laugh, or the act of laughing this way.
The young adult sniggers quietly behind a hand.

Etymology
Snigger is a variant of snicker, a half-suppressed laugh. Snicker may imitate the sound itself; the central image is laughter partly held back, fitting the quiet laugh in this sense.
In context
St Xavier’s boys sometimes brought them in by stealth to snigger over among their mates; for the language of the grateful patient recounting his symptoms is most simple and revealing.
