I have written about this before, but Michael Silverstein’s concept of indexical order is so good it makes me smile. Indexical order refers to the normativity of meaning relations: it is the ‘principle’ that bestows discourse with a particular meaning in a particular context.
Registers are a case in point. For instance, Jane Hill (2005: 114) has illustrated that mock Spanish has at least two indexicalities: a first-order indexicality that is usually associated with qualities of speakers of Spanish. However, when used by English speakers, words like ‘mañana’ can take on a pejorative second-order indexicality of laziness and ‘taking it easy’.
This sort of stereotyping also works in posh English, as illustrated by British comedian Michael McIntyre.
