A string type object in which case generally a shoe lace is used to make a lasoo type loop then tied around your head to hold your hair in place.Making sure u have only one string of the shoe lace that dangles down usualy at the back or over your shoulder. Which will make you some how look like jesus in some way. Maybe because jesus has long hair and a head band.
Person 1:hey whys that guy got a shoe lace around his head?
Person 2: nah man its cool, its a jesus string, cant u see its holding his hair down from the furious blowing winds.
