Worse than f*cked up, prone to happen when adding "tobacco" in your
blunt or using
drugs you're unfamiliar with.
Can also be to used to describe an epic f*
ck up.
Bro you were so musked up at that

Yeah man crazy
blunt did 360 all night long, then I musked up and ordered
pizza for the whole campus.
