Rolly Romero's making it clear it's totally fine for men to cry ... and he tells TMZ Sports anyone who's making fun of Ryan Garcia for his emotional outburst after their fight last week can go pound sand.

Rolando ‘Rolly’ Romero became the second fighter to defeat Ryan Garcia in a sensational upset last week. The 29-year-old from Las Vegas sent Garcia to the canvas in the second round of their bout at Times Square in New York City, before being declared the winner via unanimous decision.

Romero scored an early knockdown in the second round before cruising to a unanimous decision win over Garcia, who was fighting for the first time after his one-year suspension for testing positive for Ostarine following his win over Haney that was overturned to a no contest.
