Dynamic Duo's Choiza is creating quite the buzz lately. As images of his lost wallet have revived his dating rumors with f(x) Sulli, a video clip of his past interview has resurfaced as well. 

In this interview, the now 34-year-old talks about the origins of his interesting stage name. 'Choiza' is actually short for 'Choigang Zaji' (pronounced Che-Gang), which literally translates into 'The Greatest Penis'. All smiles, Choiza explains that he had this nickname ever since he was in his second year of middle school.

Fellow Dynamic Duo member Gaeko confirms this, stating in the clip above, "[In middle school] I would go to see Choiza during my breaks. Whenever I'd [get to his classroom], I would see three desks pushed together, and Choiza lying right on top of them. He would just lay there with his hands clasped behind his head, and there would be six students gathering around that part [of his body]. They would gather around and observe that part and touch it, saying 'Wow, how is it this big?'" With a laugh, Gaeko concludes the story, saying, "And so ever since middle school, he has been known as 'Choiza'."

With that said, this whole Choiza and Sulli thing has just gotten a bit more awkward. But hey, whether you're cringing at the thought of it, or giving Sulli all the high-fives, you gotta give Choiza some bro points for being so confident in his assets. I suppose. I mean. Right?
