instead of "you're in my hair", someone said "you're on my hair", is that right? or different meaning?

https://www.instagram.com/p/B0SVsbHJN5Z/ It seemed a hilarious one, but I just don't get it. If it wanted to say same as "I love you but you're annoying a little bit", why did it use "on my hair", or it's totally different meaning?

It's a joke.

Someone has taken an old 'Gone with the Wind' movie poster depicting a dashing Rhett Butler (Clark Gable) carrying the unconscious southern belle Scarlett O'Hara (Vivien Leigh) from a burning building and meme'd it to form a joke, albeit a little labored.

It might have been a little better if the meme was,

This rescue would go a lot smoother ... if you stopped standing on my hair.
