Miley Cyrus continues to stun fans and critics with shocking on- and off-stage antics. In fact, so baffling is her behavior that New York's Skidmore College has introduced a new course called "The Sociology of Miley Cyrus: Race, Class, Gender and Media." (No word yet on whether or not the singer will participate in the lectures.)

Miley's naughty list is miles long, but some of her racy stunts are more unforgettable than others:

1^ She posed semi-nude as a child

When she was just 15 years old, Miley was the subject of an Annie Leibovitz shoot for Vanity Fair. Her semi-topless photos caused a commotion, and the Disney star said that she felt "so embarrassed." Miley obviously got over her modesty — she was photographed flashing her bra for the paparazzi just a few months later.

2^She spits on her audience

Put Miley in any spitting contest, and she'll win hands down. The singer has had plenty of practice: one of the highlights of the Banger tour features Miley sipping water on stage and spitting it back out onto her audience. Front-row tickets don't include protective gear, so stand near the stage at your own risk.

3^She sings with her lady parts

At the Philips Arena in Atlanta, the 21-year-old superstar reclined on the hood of a car, aimed her crotch at the audience, stuck her right leg up in the air and held her microphone to her vagina. Not much was left to the imagination, as Miley's marijuana-print leotard was about two sizes too small.

4^She shows physical affection to pot

Speaking of marijuana... Miley is very open about her love of pot. When one of her backup dancers dressed like a marijuana joint, the singer showed her affection by repeatedly leg-humping the dancer. 'Nuff said.

5^She motorboats her dancers

Miley is very comfortable with breasts — she bares her own and motor-boats others'. At a show in Illinois, the singer buried her face in the ample cleavage of dancer Amazon Ashley before turning her bootylicious friend around to slap her behind. Following the concert, Miley and Ashley shared a photo of the incident along with loving sentiments via Twitter.

6^She touches herself, constantly

Miley likes feeling up her guests, and she loves feeling up herself. The underdressed, oversexed performer just cannot keep her hands away from her crotch when she's performing on stage.

7^She French kisses girls

Katy Perry sang "I Kissed a Girl," but it was Miley who made it public. The Bangerz star went with full-on lip action during her Staples Center concert in Los Angeles. Katy later indicated that she was taken aback by the oral attack.

"I just walked up to her to give her like a friendly, girl kiss, as us girls do," Katy said. "Then, she like tried to move her head and go deeper. I pulled away. God knows where that tongue has been."

8^She eats thongs

9^She twerks married men

Who could forget Miley's outrageous performance at the 2014 MTV Video Music Awards? The bear costume and nasty tongue antics were nothing compared to the then-20-year-old's grinding, groping and twerking against fellow performer Robin Thicke. Everybody who watched was pretty uncomfortable, but no one was surprised when both Miley's engagement and Robin's marriage ended shortly thereafter.

10^She wants to be taken seriously as an artist

Prior to kicking off her Bangerz tour, Miley told a variety of interviewers that she wanted people to attend her concerts and take her seriously as a vocalist. No one denies that she is a talented singer, but everything else is just so distracting.
