What is The Hilary?
1.
a dance in which the shoulders are moved up and down, the head is thrown to the left, and the hands are pointed outwards at the elbows. This dance has taken the east coast by storm. Everybody's doin it.
"Ooooohh shit, that girl is doing The Hilary. I wish she would take her clothes off."
"duuuuude, me too."
