Becca is the love interest of Evan in the teen comedy Superbad.
Becca is invited to Jules' party. Evan offers to buy her alcohol after chatting together.
At the party, Becca managed to somehow get drunk before Evan arrived. She takes him into a bedroom and almost has sex with him, but throws up and passes out. Evan leaves in disgust.
The next day, Evan and Becca meet at the shopping mall and start over.
Becca generally comes across as a very cheerful and approachable girl. She was a little stuck-up when she was younger, as seen when she calls the principal on Seth over some lewd drawings which led to some friction between them ever since. She seems to have outgrown this, as she has no reservations about drinking despite being in high school and having sex at a party.
