Becky Fleming is an unpopular kid that is invited to a party hosted by Steve and his friends in "The Unincludeds".
When Steve's making out with hot girl Lolo Fuentes makes him popular and alters a future when he and Snot are prosperous, his idea is to make Snot popular as well to restore their timeline. But Snot's attempt at small talk fails and Becky throws a childish temper tantrum for him, ruining the only party she had ever been to.
Going back upstairs to see the result of Snot's interaction with Becky, they find he has changed from simply being a bum to becoming a convict as he vowed never to speak to a woman after that, not even the ones he had eaten.
Becky is seen during Principal Lewis' end of the school year locker inspection in "The Curious Case of the Old Hole".
