person A: Hey man, did you see the look on that girl's face after I turned her cat into a jizz-cicle?

Mongolian Fishing Boots are only worn by the absolute finest uncle collectors, illegal bug fight hosts and participants, and for the people that reject Zara Employees and Tech Extremists. If you don't wear these with your best friend and you don't sneak rare fish into the Hawaiian island called "poopoo", you are failing in life.
Luca Maxim: "If you do not wear and/or make counterfeit Mongolian Fishing Boots, you are failing in life."
Some guy: "Oh shit I never knew that, thanks Luca Maxim!"
