cock spam

Random and obnoxious emails advertising penis enlargements that begin showing up in your inbox after visiting a porn site you knew you shouldn't have. Hard to filter because they were sent from an absurd address from a country with an abbreviation you never heard of before. Require awkward explanations to anyone looking over your shoulder while you check your email.

Girlfriend: What's that email about?
Guy: uh, just some stupid cock spam that I keep getting after I downloaded this thing for a project at work.
