I was watching The Real Housewives of New York City (RHONY) the other night, and noticed that Carole Radziwill said that LuAnn de Lesseps ("the Countess") was a friend jumper. I liked this term, as it's similar to friend thief, but goes beyond that to essentially try and benefit as much as you can from a friend's connections. Now, did de Lesseps really do this? We don't know. But let's talk about term some more.
Radziwill used this term to a designer friend who she had recommended to de Lesseps. Essentially, she was doing de Lesseps a favor by "setting her up" with a connection with her designer friend. Radziwill's beef with de Lesseps is that instead of being gracious, she went a step too far and asked for free clothing.
I agree, if this is the case, it's bad friendship. Even if their friendship is casual (or manufactured by a reality TV show), you don't ask for favors the minute that someone introduces you to a friend of theirs. You take time and get to know them, or you buy their stuff (in this case) but you don't ask for freebies.
The danger with being a "friend jumper" is that you'll be viewed as someone not sincere with people, and as a result, potential new friends will avoid you. Not just that, but existing friends may wonder if you've tried to get something off of one of their connections as well.
