Wu was born on June 12, 1990, in Houston, Texas. His father, Michael Wu, a Taiwanese immigrant, is a computer engineer. Wu graduated from Clements High School in Sugar Land, Texas in 2008 and attended the University of California, Davis for two years before dropping out. He was living in downtown Los Angeles while in the entertainment business but later relocated back to Houston.

Wu was severely injured in a car crash in June 2015. In May 2019, Wu completed his bachelor's degree in psychology at the University of Houston.

Wu was known for posting humorous videos on YouTube. When Wu's "I Have to Deal With Stereotypes" video was featured on YouTube's home page, his number of viewers began to increase. In this video, Wu talks about stereotypes he has to deal with as an Asian-American. He tries to disprove his cheapness by bragging about the recent purchase of a "brand new, top-of-the-line, TI-84 calculator". He acknowledges that this might make him nerdy but dismisses this stereotype too as he does not "make all A's...in school today [he] made a B+." He is then greeted by a voice that was supposed to be his mother calling him a loser and accusing him of dishonoring their family. Wu goes on to say he can prove his predominant social life with the constant ringing of his cell phone. At this point, his phone indeed rings, he answers it, and the voice on the other end to Wu's disappointment says, "Hey, why did you tell me to call you?" Wu has collaborated with fellow YouTube comedian Christine Gambito (HappySlip), making five videos with her.

Following his video, "Butthash Hero", Wu introduced his father, PapaJumba, onto his YouTube channel, and his father made several appearances in candid video clips taken by his son. Responding to Wu's father's growing popularity among viewers, his father made a debut in "I Love My Dad", and has been featured alongside his son many times since.
