A pro-wrestler who is so unable to perform basic actions correctly and at the right time, that they almost certainly are unable to wipe their arses properly, leading to them walking around with their arses being all shitty. Hence, shitarse.
Man, I just watched a match involving noted shitarse Magnus. He's fucking terrible, at everything.

Made-up Spanish verb meaning to shit yourself
Si pudea me shitar (shitarse), esa seria bueno.

If i could shit myself, that would be great.
