eaveslooking
When you sneak a peek at a secret sign language chat between two deaf people, like a trashy spy who can't even read.
I saw my teacher signing secrets to the principal. I eaveslooked like a dirty little rat.
My cousin signed to his crush. I eaveslooked and felt like a total schmuck.
I peeked at my mom and dad signing about my allowance. I eaveslooked like a greedy kid.
