2. Someone who makes others uneasy or uncomfortable, despite a normal outward presentation.

1. I usually leave my car keys on the kitchen counter, but today I found them in the refrigerator. It's been nine kinds of relish this morning.

2. That guy at the party last night seemed nice, but there was something off about him -- he was definitely nine kinds of relish. I'm glad I didn't give him my number.
