On Christmas day, BTS attended '2017 SBS Gayo Daejun' and lit the stage with hot performances of "DNA", "Not Today", and "MIC Drop". 

Among the performances, SUGA's bold action during the "MIC Drop" stage is gaining much attention. During his solo rap part, SUGA suddenly puts down his mic and purposely remained silent where he was supposed to say, "If you're sour, just go ahead and sue me. Sue it."

He then stares at the camera and lets out a mischevious smirk while the stage is filled with silence. 

Fans believe SUGA made such an action to shut down all the haters accusing BTS of lip syncing. 

Netizens were impressed by SUGA's clever way of clapping back at the haters and commented, "The stage was totally dominating!! They are really the best", "This is a gesture for the people who say it's lip syncing or recorded lol He definitely proved it's all live", "Wow... I'm getting goosebumps... They are so cool."
