What's a good American Sign Language sign for my older sister? Only answered by the DEAF please!?

I want to give my sister a name in sign language. My stepmom was given the name bug because she likes ladybugs. And no, don't feel bad or anything because no one in my family is deaf. I'd just like to have another way of communication so I can talk to the deaf. My sisiter is nice and stuff so think think think. And if you aren't deaf, then sorry. Only a question for the deaf. AND DON'T pretend to be deaf. That's rude and hurtful.
