Circa 1982 - Refers originally to glass crack pipes and how they were dropped while being passed around a circle of people.
Then with the popularity of urban culture came to be associated with anything "hot".

It comes from a Lil Wayne song. He wants the girls to drop their asses to the floor while dancing. Also, when something is hot you usually drop it.

Hence "drop it like it's hot"

Taking a big dump; pooping

When you keep name dropping to sound cool.

Could it mean when your balls are hot and they drop away from the body?

A phrase that Snoop Dogg originally sung in the song labelled such, ascending on the word hot'. Due to the hillarity in the way it sounds, it just makes rap-type music sound inane. It is fun to say though.
