If you know the difference between the middle finger clap and the index finger clap, congratulations! You've lived through at least two dance eras. 😂 And just in case you're also "old" like me: the index finger clap means "clock it" and the middle finger clap means "ate" (as in eight in sign language) and can be used to clap for someone.👌🏽👏🏽 Fun fact: finger claps actually originated in the 1960s, so once again, the youth are just making old things cool again.☺️ #fridayfun #clockit #ate | J
