To cut yourself up and down the artery, as opposed to across the street (across your wrist artery)
Emo kid: I'm gonna take my knife and walk down the street
2nd Emo: Alright, see you there mi hombre *takes knife and cuts self and dies and bleeds to death*

A euphemism for slutty behavior. The phrase comes from a story about a girl who went to her ex boyfriends house after the bar one night and when his new girlfriend showed up he kicked her out the back window and made her walk home.
If she keeps drinking like that she'll be "walking down Knight Street" by 10:00.
