Stereotypical situation when a new girl joins a group, class, etc. And most guys in the group immediately tries to impress her, hit on her, get to know her, etc.

Taken from the comic The Smurfs where Smurfette moves to the male dominant city of the smurfs and all the smurfs there immediately tries to be with her.
- There was this new girl in class and every guy wanted to be with her!

- Oh, the smurfette effect!
