look up any word, like hipster:
 
1.
American music group from Gary Indiana that emerged onto the pop scene in late 1969. They scored 4 early number ones and were considered the top musical act of 1970. They went on to have a successful career at Motown until they switched to the Epic Records label under their new name, The Jacksons, in 1976.
The Jackson 5's music will never get old. How did the young Jacksons know how to sing that well?

2.
$100 in 20 dollar bills. Since Andrew Jackson is on the face of a 20 dollar bill and it takes 5-20 dollar bills to make 100 then it is a Jackson 5.
