eaveslooking
Peeking over someone's shoulder like a sneaky bug, especially when they don’t even know you're there.
I eaveslooked my brother while he was texting his crush. I felt like a sneaky little bug.
My friend eaveslooked me while I was typing a mean text. I caught her like a rat.
I peeked over my neighbor's shoulder while he was signing to his dog. I eaveslooked like a weirdo.
