gäng signs

"Throwing up" a gäng sign (or "Stacking") with the hands is one of the most known and obvious forms of "claiming." It is used in many situations where other identifiers may not be possible or appropriate, and can also show that a gäng member is in the area to "do business" as opposed to just passing through. Usually these signs are made by formation of the fingers on one or both hands to make some sort of symbol or letter. (en.wikipedia.org)
