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"

Get the Drop it like it's hot mug.
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.
