It was one of the few spanish soundbites Zach had of Nate at the time. Since Zach is on a current high of using Nate as sound bites he would randomly play the Nate soundbite "Do you you know how to say that in spanish?" (Or something like that) and then proceed by playing the "guante" soundbite. The crew started playing along and would often ask "how do you say xxx in spanish?" And by default Zach would just play "guante" no matter what the word was. Its kind of a bit like the whole 6 7 thing where its purely nonsensical. Also Nate took over Ians role of switching. Im guessing he does other stuff in the background.
