To analyze the effects under the development of meaning, valuation and carnivalization from the elaboration of laughter in the humorous comic stories of “Um Sábado Qualquer” (henceforth USQ), created by Carlos Ruas, posted on the social network Instagram, is the main objective of this thesis. For that, we used the concepts of evaluating tone and carnivalization, theorized by Círculo de Bakhtin (2008; 2010; 2014; 2015; 2016), some studies about comic stories as a genre organized by Santos (2002), Ramos (2009; 2013; 2017), Franco (2004; 2013) and McCloud (2005), and the perspectives regarding laughter presented by Minois (2003), Bergson (1900/ 2018), Freud (1905/2017) and Lima (2019).

Absurd in the humorous comic stories emphasizes the movements of valuation and carnivalization from the religious Jewish-Christian speech. Through the redirection of social events and facts from the social imagery, axiological approaches are linguistically and visually materialized in the comic stories. The carnivalized cosmovision occurs through aspects such as the familiar contact, the downgrading, the dethronement and the desecration of an image of the Lord/ Father/ Almighty and the inversion of some ...
