This is how you sign Unfriendly in American Sign Language.

Description

To sign "Unfriendly" in American Sign Language (ASL), wiggle your fingers while moving both hands backwards. Begin the sign a few inches in front of your head and continue moving back until your hands are level with, or slightly behind, your face. Accompany this with a negation sign, which is a slight shake of the head, to express "not" or the lack of friendliness.
