Many emotive taboo words or phrases, despite having nothing in common semantically, can substitute for each other syntactically
Many (nonsensical) modern taboo expressions come from originally historical religious expressions that lost their emotive power → frigative substitution
e.g. Damn you → fuck you, Holy God/Jesus → holy shit
Profanity → obscenity and scatology
Happens in other languages too
In these constructions, semantic meaning plays no role in uniting
All taboo
Taboo words can give insight into grammatical constructions not evident in non-taboo lexicon
