snicker — give a smothered or half-suppressed laugh; snigger.
ORIGIN imitative (: reproducing a natural sound).
My post-college best friend and I got to know each other because, like so many before him, he was drawn to my total lack of interest in just about everyone around me. (As we’ve discussed before, this is because I don’t like strangers.)
Back when I was employed in the US, I was temporarily assigned to the cubicle next to his. He quickly found himself trying to see what I was doing since, to hear him tell it, there was a steady stream of snickering coming from my side of the particle board. Whenever he was able to casually figure out what I was reading, he’d try to find the same article and see what was so damn funny. Most of the time, he couldn’t understand what was so entertaining in the A-section of the New York Times but he marveled at my consistent amusement.
Once we got to know each other better, he learned that the mystery of my mirth is that I find the funny in everything, a variation on that all-time great whistling anthem. (C’mon! It’s been ages since I mentioned the Python boys!)
