Richarlison told Liverpool legend and prominent pundit Jamie Carragher to "wash your mouth" and "I don't respect you" after helping Everton secure Premier League survival.
The Toffees were in a desperate situation at half-time of Thursday's clash with Crystal Palace at Goodison Park, trailing 2-0 to goals from Jean-Philippe Mateta and Jordan Ayew.
However, Michael Keane reduced the deficit and Richarlison equalised to set up a blockbuster finish that saw Dominic Calvert-Lewin score an 85th-minute winner to ensure Frank Lampard's side staved off relegation with a game to spare.
Ex-Liverpool defender Carragher has taken aim at Richarlison in the past, particularly over what he perceived to be play-acting in matches against Liverpool and Chelsea.
Carragher, a former England defender, later wrote on social media that his assessment of the Brazil forward was "nothing to do with bias".
But Richarlison clearly has not forgotten the criticism and took the opportunity to hit back at Carragher.
He posted on Twitter: "Wash your mouth before you talk about me and Everton and I don't respect you."
Everton round out their season with a trip to Arsenal on Sunday, with the Gunners needing a win to have any hope of beating rivals Tottenham in the race for the top four.
