Two people in paired movie or horror costumes film one fixed shot to the beat: one poses in character, then they turn back to back and the other takes the front. It is an easy way to show off a couples costume with a reveal. The comments are mostly about how unrecognizable the creators look and how accurate the costumes are.
Dressed as Bruce with the chocolate cake and Miss Trunchbull from Matilda, the pair swap places on the beat in their living room. The Trunchbull teeth steal it. With over 180 million plays, people call these real costumes and share their own family versions.
Nikki and friends go full Shrek: Lord Farquaad, Shrek and Donkey take turns at the front of the frame. Big cast, big makeup. Comments say they didn't recognize any of them at first.
Two friends as a royal pair in blue armor and a purple gown spin back to back and trade the spotlight. The serious faces make it funny. A short, simple version that shows how easy the format is.
