A woman was horrified after she noticed a 'rude' detail in her bikini photo.
Eager to get a "cute" picture for Instagram, Madi Marotta posed in a yellow two-piece swimsuit at Miami's South Beach.
But, unbeknown to her, a woman's arm in the background made it look like she'd grown an X-rated appendage.
Madi shared the picture on TikTok, where she's known as @madimarotta, and it quickly racked up more than four million views from people who labelled it the "best TikTok I've seen."
She said: "I tried to take a cute pic on South Beach and this lady’s arm makes me look like my peen is hanging out. Enjoy."

Since being posted, the video has received almost 700,000 likes and 11,800 comments from people who were left in hysterics.
Madi was also inundated with messages from viewers who offered to photoshop the woman's arm out of her picture.
One person said: "Well, there’s always Photoshop."

Another wrote: "I WASN'T EXPECTING IT TO BE THAT BAD."
"I just laughed out loud," said a third.
Whilst someone else put: "Reminder: don't take pictures in front of peoples arms. Ok, got it."
In later videos, Madi said that she had actually posted the original picture on Instagram to see whether anyone would notice.
But "within five seconds" she was receiving texts from her friends about the rude detail so she decided to delete it.
