look up any word, like bukkake:
Using someone else's Wi-Fi (wireless internet) to access the internet. Although this is not safe and completely insecure, it's cheap and worth the risk if you're just checking the $3.00 in your bank account or applying for a loan with your Social Security Number and mother's maiden name.
