So-called arm vagina appears to be the latest body shaming issue for female celebrities on the red carpet to worry about, and people are concerned that teenage girls will be affected by yet another unrealistic body standard.

The term was first coined by Jennifer Lawrence back in January 2014. On the SAG Awards red carpet, Lawrence was disparaging about the arm creases created by her tight sequined Dior dress.

Speaking to E!'s Giuliana Rancic, who complimented the dress, Lawrence joked: 'I know I have armpit fat, it's OK... it's armpit vaginas." She told CNN at the same event that her dress was "squeezing her breasts into her armpits".

Arm vagina was then listed as a phrase in Urban Dictionary. The definition reads: "That fold of skin where a woman's arm joins her torso. Can be present even in relatively fit women." Alternative phrases given are chicken skin, labia pit, fungus fold, armpit waddle and rooster arm.

Now, almost four years later, arm vaginas are reportedly one of the body issues most worrying women on Hollywood's red carpets, as celebrity stylist Rebecca Corbin-Murray said while discussing her clients' most common insecurities with The Times this week.

She said: "Sometimes it's the weirdest part of their body. They say, 'I've got this horrible blah-blah', and you think, 'What are they even talking about?' The one that comes up all the time is arm vagina."

The comments were picked up in a comment piece by The Guardian on Friday (1 December), describing the "bonkers, unreal, insane" arm vagina worry as Hollywood's "latest form of female self-flagellation". Gaby Hinsliff wrote: "Merely having abs that could crack walnuts and a face betraying no sign of human ageing isn't good enough any more – presumably on the grounds that nothing is ever good enough for women making a living in the public eye, and consequently for self-conscious teenagers striving to copy them."

Others then began to share the fear that young girls and women would struggle with yet another unrealistic body expectation exhibited by their favourite celebrities. BBC presenter Jeremy Vine said "this is mad" and women reacted on Twitter by questioning "Will we EVER learn to love ourselves?" and "Is it any wonder women and girls are as insecure about their bodies?"

Karen May, senior lecturer at the School of Health Sciences, University of Central Lancashire, said: "I have been qualified as a physiotherapist for 27 years and have never come across an "arm vagina"! And i teach anatomy! Help am I missing something or has the world taken another turn towards madness?"
