|1.||Get your license upgraded|
Euphemism for getting a girlfriend.
Stems from the idea that upgrading one's probationary license to a full license signifies maturation; as would the entering of an 'adult' or legitimate relationship.
Dude, you should grow up and get your license upgraded.
What do you mean, I hardly drive.
No...dude you need to keep up on your lingo--get a girlfriend.
