The act where by someone befriends you, they seem legit as you share a few friends with similar interest or are part of a similar community, then you notice the sniper picking up other friends of yours that have no connection to the sniper other than yourself.

I started getting asked who this person was asking to connect with a lot of my friends. I think they're friendsniping.
