They meet the notorious street gang, called the Crips. Timmy and Jimmy were accepted into the gang, on the one condition that they "they pop some punk ass bloods". After they inadvertently cause a traffic accident, killing thirteen of the Bloods standing in a parking lot, they are accepted and given new names. Jimmy's nickname becomes "4-legs" while Timmy's is "Roller". This action prompts the Bloods to retaliate by trying to kill Timmy and Jimmy in a drive-by shooting at their houses. To resolve this conflict, Jimmy rents South Park's Recreation Center and invites both gangs to an all night lock-in, until they resolve their differences. Both gangs realize they have many things in common. Beginning a friendship, they play basketball and sing songs together, thus having a general good time.
The Crips wear blue handkerchiefs, blue clothes, and have many tattoos.
- The Crips are a real street gang with members all around the world numbering in the tens of thousands.
