A moonquake is an earthquake, but on the moon. It means that there could be something underneath the moon's surface causing the event to happen. Moonquakes are measured by rovers.
Term coined to describe someone who is annoying, obnoxious, intentionally ignorant and - most importantly - squeaky of voice. So squeaky, in fact, you can probably hear them several rooms away (or they're so annoying, you'd CLAIM to anyway).
"Oh, God, not Squeaky McSqueakers again! He/She really makes me just wanna...ARGH!"
