Similar to Mario Karted, where you go from first or second to a bottom spot in a stupid way. Based off the voice clip from Mario Kart 64.
Person 1: *gets knocked from first to last by a Blue Shell and an army of reds* FUUUUUUUUUUUUU
Person 2: Welcome to Mario Kart!
Something to say to your friend when they get Mario Karted.
Dave: wtf bro i just dropped to last place
John: Welcome to Mario Kart
