2 Girls 1 Cup is the unofficial nickname of the trailer for Hungry Bitches, a 2007 Brazilian scat fetish pornographic film produced by MFX Media. The trailer features two women defecating into a cup, taking turns in what appears to be consuming the excrement, and vomiting into each other's mouths. "Lover's Theme" by Hervé Roy plays throughout the video.

The video became one of the best-known shock videos in itself and for the reactions its graphic content elicited from viewers who had not seen it before. Around mid-October 2007, video-sharing sites including YouTube were flooded with videos of the reactions of first-time viewers.
