titter (v.) – to laugh nervously or self-consciously
for your edification: Say this word out loud. Titter. Heh heh. Heh heh. It sounded like you just said “tit her.” Heh heh. Heh. Sorry I’m laughing so nervously and/or self-consciously. It’s just that you just said “titter.” Heh heh. I’m embarrassed for you, and a little for me, too. You just said titter. Did I mention just how much that sounds just like “tit her”? It freaking does! That totally makes me titter. Heh heh.
Examplification – Larry: Hey, man. Why are you sitting outside the principal’s office?
Skinny Jim: It’s not my fault. Mrs. Womack totally set me up. She kept talking about some dude tittering in this stupid story we’re reading.
Larry: It’s a funny word. Were you embarrassed or something and you started laughing nervously or self-consciously?
Skinny Jim: No. Why? I got in trouble for asking if I could grab Cheryl Lampkins’ titters.
Larry: Gotcha.
