The article provides an outline of the sociolinguistic, cultural and linguistic determinants of the use of colloquialisms in the modern Polish language. 37 protest signs from the 2020 Women’s Strike in Poland with an invective meaning semantically related to specific people and organizations were analyzed. In order to analyze the similarities and differences between the presented examples, the semantic field method was used. Based on the specific characteristics of the analyzed expressions, 13 semantic microfields were distinguished. The innovativeness of the study consists in looking at the invective not only as an example of using verbal aggressiveness, but also as a peculiar wordplay which, paradoxically, may facilitate communication and relieve tension.
