Blason populaire
Blason populaire is an umbrella genre in the field of folkloristics used to designate any item of any genre which makes use of stereotypes, usually, but not always, negative stereotypes, of a particular group. "These stereotypes are manifested in a wide array of folkloric genres, including proverbs, other traditional sayings, nicknames, jokes, songs, rhymes, and football chants. All share a common function in that they are invoked to highlight positive aspects of the in-group by explicit auto-stereotyping or, alternatively, to identify the negative characteristics of out-groups. The explicit positive stereotyping of an in-group may often implicitly suggest negative characteristics of a rival out-group." In blasons populaires nations are homogeneous and have national characteristics.
Items such as ethnic jokes or blonde jokes are very common examples of blason populaire.
