Can't have shit in is a phrase users say online, it has a US state after the "in" part (it varies with any state).
It originally started out after someone posted a picture of their
house and their porch missing on
Facebook captioning it with, "Opened the door 🚪 and fell I’m pissed 😤 Can’t have shit in Cincinnati mfs done stole my porch bra 😠". Someone then re-posted it and re-captioned it to ,"Someone stole my fucking porch . I opened my door an fell 🤦 ♂️ u can't have shit in
Detroit". The "Can't have shit in" phrase spread
like wildfire with it varying between US states/cities. It points to the fact that you can't have shit anywhere without some mf taking it even if it has the littlest value to it, it also points to the fact mfs
will just steal the most obcure random thing.
