Not clear what distinction you’re drawing—if the latter is the effect itself, then it describes it by definition; the question is what’s the cause, of which “social proof” is one possible. Or how were you thinking about it?
I wonder… is this a “social proof” a.k.a. Magnetic Girlfriend effect? (If you have one girl hanging on you, others become interested?)
Edit: Rephrased to fix ambiguity.
Warning: “Magnetic Girlfriend” is a TV Tropes link.
Definitely not. If I shake myself free and go to another room alone, it works just as strongly.

Fixed, sorry. (Two different names for the same basic thing.)
