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!"
