so maybe pinch- punch is an Irish thing. We played it in school in England around the same time -in the late fifties and early sixties when over the half the class in Catholic schools were second generation Irish. Nudcat Anglophiles maybe didn't play such crude games ! We also had the monkey bumps but our burns were Chinese , not Indian .And we were all delinquents as well but not delinquent enough for the titty whizzle or "LSMFT"-whatever tf they were!
