Victims’ reactions to the prank vary between angry, confused and, in one case, entirely oblivious

Could these be the world’s most annoying pranksters?

Three teens from Northern Virginia calling themselves the Chaizy Channel have filmed themselves squirting shampoo into people’s hair as they shower on the beach.

The stunt, imaginatively entitled the “Shampooing Strangers Prank” sees the three irritants sneak up behind an unsuspecting beach goer and add some extra cleanser to their heads as they wash.
