To quickly parallel park.
The phrase originated from a tactic used to evade the
police. The driver, after getting out of view of the
police, would rapidly parallel park and
duck down so that passing cops would most likely bypass.
The phrase was made famous in Snoop Dogg'
s song "Drop it Like It's Hot". When he uses the line, he makes a steering motion with his hand, similar to motion taught to drivers learning how to parallel park
"360 to the right, 360 to the left".
"Park It Like It's Hot" then means to park quickly even though you aren't being pursued.
"Hot" in this case is used to suggest that the
car is stolen.
