A person who by society's description doesn't fit in with their friend group, being more approachable, and the one to go to ask for their friends numbers.
Guy: Heyyyyy

Duff:(THINKING: OMG HE's TALKING TO ME> HE'S SO HOT) Yes? What

Guy: Well, i was thinking... would you like to...

Duff: Yeah...?

Guy: What's the hot girl on the left that you were talking too's number...?
