Top definition
A guy who is stuck in the late 90's thug life. Can't seem to get the pimp out of his walk. A Nilsen's pants are not intentionally baggy, just a rare find at the local thrift shop. Wakes up every morning to Ice Cube's "Today Was A Good Day"
Look at that white guy getting beaten up in the black neighborhood. He's a nilsen.
