Mario is the central character of Nintendo's long running game series, and short voice clips of his lines are widely reused outside the games as reaction sounds. This truncated give me your line spread through user soundboards and short video edits because the cut off ending can be applied to almost any object. Its brevity makes it easy to loop, layer over gameplay, or drop into chats, and it remains popular for the same reason many game voice memes do, the joke is completed by whatever the creator shows next on screen.
