Remote dance refers to the movements you make with your hand when trying to get your TV to recognize your remote control.
“遥控舞”指为了让电视机对手中的遥控器有反应而做出的各种动作。
All remote dances are different, but most involve twisting your hand around until the remote is almost upside down, thinking that for some reason that will help.
“遥控舞”各有不同，不过大部分都有翻转手臂的动作，直到遥控器正面差不多被翻过来，总觉得这样能管点用。
For example:
Last night I remote danced for like five minutes trying to turn the volume up.
昨晚，我为了调高电视音量，差不多遥控舞了5分钟。
