A modifier used to intensify a command. Slightly more powerful than "your ass." Appending "bitch" onto the end of the sentence further strengthens the emphasis as well as the condescending power.
From most polite to most offensive/aggressive:
"Please sit down if you would be so kind."
"Sit down, please."
"Sit down."
"Sit your ass down!"
"Sit the fuck down!"
"Sit the fuck down, bitch!"
"Please sit down if you would be so kind."
"Sit down, please."
"Sit down."
"Sit your ass down!"
"Sit the fuck down!"
"Sit the fuck down, bitch!"
