When something bad happens to someone else, that we secretly find amusing'ish. Or in reverse - it can be used when
u are really feeling sad / bad for
the shit that someone else is going thru... and u can't kinda say what
u really want to.
You - "I've just found out that i have to empty my grandmothers cholostemy
bags for a month"
Me " Ha,
sucks to be you!!"
You - " Hey, just found out i've got leukemia"
Me - "
Oh ... sucks to be you, right now"
