Sock.

When Jerry (30s) masturbates into it one too many times, his crusty old sock comes to life and immediately declares its love for Jerry. This newfound sentience causes a problem when Jerry’s girlfriend Claire demands he throw the disgusting thing away. Sock and Jerry convince Claire to keep Sock around, as Sock promises to help get their relationship back on track. However, once Jerry and Claire begin to resolve their issues and need Sock less, Sock’s jealousy turns to rage and blood-soaked vengeance.
