When one friend befriends another through your introduction, soon putting more effort into that
person than you do, simultaneously making you seem less desirable and devaluing both your
original friendships. This can happen consciously or unconsciously. Notably, one does not tend to ever make any new
friends for themselves through the friend poacher.
I used to be close with Guy until I introduced him to Buddy, who started inviting him out all the
time; I think Buddy is friend
poaching, especially considering I've
never met any good friends through him.
