By the 1930s, "there was no more damning insult than to be called a sissy" and the word was widely used by American football coaches and sports writers to disparage rival teams and encourage ferocious player behavior.[11] The use of the word sissy was "ubiquitous" among delinquent American youth of the 1930s; the term was used to provoke boys to join gangs, demean boys who violated group norms, force compliance with the mandates of masculinity, and justify violence (including sexual violence) against younger and weaker children.[12] Good students were taunted as sissies and clothing styles associated with higher social classes were demeaned as sissified. Among members of a Detroit youth gang in 1938-39, sissy was "the ultimate slur" used to tease and taunt other boys, as a rationalization for violence against rivals, and as an excuse for not observing the dictums of middle-class decorum and morality.[12]
