in my opinion it just figuratively corresponds to the importance of doing something unexpected to modern, it is said that the pond in question is "pwnd" see also "aybabtu" or "gotcha" or "fair cop" linguists claim that "burn the pond" is related to the command " burning ", which means that onlookers can throw themselves into the pond and pick up the remaining fish for free after the catch, but that doesn't seem like much to me.
