IShowSpeed accidentally flashes his penis to thousands of fans ...

IShowSpeed showed a little bit more... speed during his recent YouTube live stream.

The popular gamer and internet streamer was playing Five Nights at Freddy's when the character 'Chica' appeared on screen.

The YouTuber, who has over 19 million subscribers, stood up and thrusted in front of the camera.

"Oh, Chica, I miss you," he apparently said. "I'm about to f*** you, Chica. Oh s***, this d*** up in you, baby."

Then his penis slipped out of his shorts.

"Oh my God, oh my God," Speed, whose real name is Darren Watkins Jr, said before cutting the stream short.

Speed was probably panicking as showing nudity on YouTube could end up getting his account removed.

According to YouTube, content that includes 'the depiction of clothed or unclothed genitals, breasts, or buttocks that are meant for sexual gratification', is banned, including 'the depiction of sexual acts, or fetishes that are meant for sexual gratification'.

The mishap happened just days after IShowSpeed returned to the platform following ill health.

Last month, he suffered a severe sinus infection that left his right eye swollen shut.

He was also diagnosed with cluster headaches, which are a result of a rare condition that causes random, painful headaches on one side of the head.

"I have this thing called a cluster headache right now. A deadly headache disease," he said in a video.

"I can't sleep, I can't eat, I can't do anything right now."

When he was later hospitalised in Tokyo, fans gathered outside the hospital and chanted his name.

Others shared messages of support on his channel.

"It’s OK Speed, just know you have all of us here with you to support and pray for you. I hope you feel much better," one subscriber wrote.

Another added: "Take a break from everything. Just relax. That will most likely help a lot. We love you and support you!"

A third said: "Things like this show us that streamers are human too and we gotta respect them, and especially protect Speed at all costs. Sending my prayers, you're gonna get out soon Speed."

Speed returned to the platform on August 15, just in time to celebrate hitting 19 million followers.
