Final answer:
A double bagger is a slang term used to describe someone unattractive.
Step-by-step explanation:
A double bagger is a slang term commonly used when referring to someone who is deemed unattractive. It is typically used humorously or in a self-deprecating manner. The term comes from the idea that someone who is considered unattractive would need to wear a bag over their head to cover their face, and even an additional bag over their partner's head to avoid seeing their partner's face.
It is important to note that this term is considered derogatory and offensive, and should not be used to describe or insult anyone.
