To smoke weed, and someone says something really trippy and you get into a deep talk about it..

Killing someone in your own gang, but who is in a different set. i.e. a different street but in the same gang

Set tripping is actually the act of hanging with a set that isnt of your own. Like a 83rd street crip hanging with (and pulling out missions with) a shotgun crip.

To trip over the set (street, block, area) you claim.
To become violent towards a gang or crew.

Bring violence in the name of your gang. Gang violence.

"Sets" are refrences to street gangs. Set tripping is violent results from the confrontation of two rival gangs or gang members. Gang members identify eachother by tattoos, hand signs, and colors worn. Gang members or gangbangers rarley hesitate to attack another gang member who represents a rival gang.

To affiliate yourself with several different gangs without belonging to one particular gang.
