That means you extra or to much to even handle

Something you would say to someone who is being rude or is in a shitty mood.

similar to who shit in your cereal.

It suggests they are trying to slide in your dms, so people will say i like your phone case to start a conversation with you And then decide that they want to play hard to get and leave you on read.

When someone is on anothr's case it means he can be stalkingthem or following them... juss looking at wat they are doing

What's up, how are you, what's happening, what's going on, what are you up to, what are you doing etc.
